How to control impurities has been one of the greatest concerns in the pharmaceutical industry.

Proper understanding of pharmaceutical impurities is super important when it comes to developing a drug from scratch. If impurities exist at the end of the development process, it can have severe pharmacological and toxic effects, such as reducing the quality of the product and jeopardizing patient safety.

You may be asking, “What are pharmaceutical impurities?”

Here is all you need to know about it

What are impurities?

Impurities are simply chemical substances that are restricted in an amount of liquid, gas, or solid, and that is different from the main composition of that substance.

The International Conference on Harmonization (ICH), which is working on creating suitable guidelines for impurity control, defines impurities as a part of the new drug substance that is not part of the chemical entity of that new drug substance.

In simple terms, impurities are unwanted chemicals that either mix with the active ingredients are formed during drug development or form upon aging. Anything that is not part of the main substance is an impurity.

The amount of impurity doesn’t affect its power. Their presence even in tiny amounts can adversely affect the safety and efficiency of the pharmaceutical products.

There has been lots of increasing research and studies on the impurity profile on drugs, because of various regulations provided by international bodies.

How are Impurities classified?

There are different ways impurities can be classified. They are:

1. By their common names: Degradation products, interaction products, related products, transformation products, by-products, intermediates, penultimate intermediates, etc.
2. By ICH terms: The ICH has a unique way of classifying impurities such as- residual solvents, organic impurities, and inorganic impurities. Note that these impurities can either be drug or process related.
3.  United States Pharmacopeia: the USP groups impurities as Ordinary impurities, Organic Volatile impurities, and Impurities in official articles.

You can also classify organic impurities if they develop during the production or process stages, and they may be by-products, intermediates (otherwise known as starting materials), or degradation products.

How can impurities be formed?

You would most likely find impurities in active pharmaceutical ingredients (APIs), unless the manufacturers exercise caution during every step of the synthesis. For instance, there is normally a test for p-aminophenol, which could act as an intermediate for a manufacturer in the production of paracetamol.

Impurities can also be created from the degradation of the product, especially when producing bulk drugs. For instance, cephalosporin and penicillin are great examples of degradation products.

What about destructive impurities?

Impurities can influence the effects of the product, even though they exist in trace amounts. It’s safe to say that impurities can be termed ‘destructive’ when they interfere or block the working nature of the product.

You can remove impurities by both physical and chemical means, depending on the manufacturing conditions the substance was subjected to. Most times, it is done chemically. However, it is impossible to remove impurities completely because of its thermodynamic nature.   

Overmolding is a process whereby one product is made using two or more materials. Typically, the (TPE)  is often molded over another material. In this article, we look at overmolding materials and overmolding in general.

The base material is commonly referred to as the substrate, and the overmold materials entirely or partially cover it during the manufacturing process. In connection to that, over-molding is categorized into three main types. They include:

• Insert Molding

This procedure is popularly used to mold soft elastomers over rigid plastics. Insert molding is the most affordable form of overmolding. Ordinarily, the base material is placed in the injection mold and covered with a hot molding material resulting in an assembled product. The elastomer must be sufficiently subjected to some heat.

• Two-shot Molding

As the name suggests, the two-shot molding is an overmolding technique that needs two injection molding machines. The hard components are inserted into the molding machine, and the elastomer is added.

The substrate is heated to a gel or semi-solid state. It’s then transferred to the second machine, and the process is repeated. The molds should feature the intended shape of the final product. It’s should also promote mechanical bonding.

Co-injection Molding

Although both the hard component and the elastomer are forced into one mold in co-injection, you must ensure the materials are compatible. The process is also carefully monitored.

Compared to the first two methods, co-injection is more costly and difficult to control. But since both elastomers are in a completely molten state, the bond created is robust, resulting in high-quality products.

Overmolding Materials

In overmolding, there are endless combinations of substrates and over-molded materials. Adhesion and compatibility are the most critical factors to look at when selecting the pairs. It’s also vital to control the thickness of the over-molded material.

The materials used during the process must be thermally and chemically compatible. Metals substrates are compatible with any plastic mold, but you may encounter challenges incompatibility when overmolding plastic with plastic.

If the materials aren’t compatible, you’ll end up with a deformed or inferior quality product. Fortunately, you can implement mechanical bonding features if chemical bonding isn’t possible.

Some of the materials used in overmolding include:

• HDPE(high-density polyethylene)
• ABS(acrylonitrile butadiene styrene)
• PEEK( polyetheretherketone)
• PEI(polyetherimide)
• POM (Acetal Copolymer)

Choosing the appropriate overmolding material is crucial to producing high-quality products that will remain competitive in the market. Since the possible material combinations are innumerable, you may be overwhelmed with what to use.

In this case, it’s advisable to seek the opinion of a resin expert. The specialist will advise you on the bonding compatibilities, inherent properties, cost, regulatory compliance, and appearance, including other critical aspects.

Besides, you can rely on information from the overmolding materials manufacturers; they usually provide compatibility charts.

Final Thoughts- Why Overmolding

Overmolding helps manufacturers to add a soft-touch exterior to products. This aspect improves the feel or grip besides providing appealing designs to attract customers.

The procedure also helps to come up with products that can withstand vibration, UV light, and offer electrical insulation.

These factors increase the usability and durability of the products. Overmolding enhances customer satisfaction and lowers production costs.

MT ferrules were developed several years ago and are widely used around the world. It is a plastic, multi-fiber ferrule that is widely used in AOC connectors and MPO connectors. The most common ones are 12 and 24-fiber MT ferrules.

This is a guide, so each term will be explained in detail.

You may be wondering what MT is. MT means mechanical transfer. A ferrule means an object (or a number of objects, thereof) that can be used to join, seal, fasten, and reinforce. The term “ferrule” is a combination of the Latin word ‘ferrum’ which means iron, and ‘viriola’ which means small bracelet.

Therefore, a ferrule is a narrow circular ring often made from metal, and less commonly, plastic. If you work in a telecommunications or data network industry, ferrules aren’t new to you. But if you don’t, and have probably heard words like grommets or eyelets in the manufacturing industry, they are simply referring to ferrules.

Ferrules are often used to protect all or parts of cables from environmental damages, elements, thermal factors, and electromagnetic pulses. It is also used to cover parts to avoid damage and add resistance. It can also be used as a connector to connect structural devices and wires.

Ferrules are also used to bind parts together. These parts include cloth threads, a bundle of wires, etc.

MT Ferrules

MT ferrules are made from multi-core polyphenylene sulfide. It is aligned in such a way that two stainless steel guide pins fit perfectly into the alignment holes. These ferrules are used in multiple optical connectors like MPO connectors and QSFP+ transceivers. They are also appropriate for active or passive fiber coupling designs.

Data centers and telecom companies understand the importance of MT ferules in their line of work. This is why it’s very important to get high-quality ferrules from reputable companies.

This is what FSG aims to achieve.

FSG is one of the world’s leading MPO experts and MT ferrules manufacturer. They are one of the most reputable and respectable companies, and a lot of data networks and telecom companies trust their judgment. Their quality of products and services has always been top-notch.

They have never disappointed their customers with the quality of their work, and they aren’t about to start any time soon.

The MT ferrules that FSG produces are highly stable and made from polyphenylene sulfide (PPS) that allows fiber tips to be protruded. The polishing time and force are reduced as well, which causes high-grade end-face geometry.

FSG produces ferrules from 2, 4, 8, 12, to 24 cores. However, 12 and 24-fiber MT ferrule are popularly used. FSG secures fiber to these ferrules through an optical connector.

MT Ferrules are important components in high-density fiber components and assembled in optical transceivers and modules. FSG has also produced MT ferrules in recent years that can be used in HDMI 2.1 cables.

Different parameters are noted carefully during production- hole diameter, type, eccentricity, guide pinhole diameter, fiber mode, insertion loss, and return loss.

A molecular weight calculator is an online tool that is used to calculate the molecular weight. Molecular weight is a measure of the total value of the atomic weight of the atoms in a molecule. It’s also referred to as molar mass and defined as the mass of any sample divided by the substance mole in a sample. Another less common definition of molar weight is an average of many instances of a compound. Molar mass is gotten by dividing the mass of a substance by its molecular value. The SI unit of molecular mass is grams per mol^-1. It can also be presented as kilograms per mol ^-1. To understand the concept of molar weight, you first need to understand the definition of come terms associated with the concept.

Definition of important terms associated with molar mass or molar weight

• Chemical compound- a chemical compound is a chemical substance that is composed of several identical molecules. The molecules are composed of atoms from several elements. The elements are bound together by a chemical bond.

• Chemical bond- a chemical bond can be defined as a strong attraction between different chemical elements like atoms, ions, and molecules. Chemical bonds are responsible for the formation of chemical compounds. There are three types of chemical bonds; covalent and ionic and metallic. Ionic bonds are those that occur as a result of electrostatic force, while covalent bonds are a result of sharing on electrons.

• Molecule- a molecule is an electrically neutral group of a couple of atoms that are bound by a chemical bond or more.

• Atoms– an atom is the smallest and the most constituent of standard matter. An atom constitutes a chemical element. All forms of matter (liquid, gas, solid, and plasma) are composed of either neutral or ionized atoms. Ionized atoms are those that get their positive or negative charge from gaining or losing electrons.

• Standard atomic weight- this is the mathematical mean of the relative atomic mass of an isotope. The relationship between molar mass and standard atomic weight is that it is computed from the standard atomic weights of isotopes that constitute the atoms in the earth.

• Atomic weight- there is a very small difference between standard atomic weight and atomic weight. Atomic weight refers to the mass is a single atom of an element or the average mass of an atom as it is found naturally on the surface of the earth.

• Isotope- an isotope is a variant of a specific chemical element. It can also be defined as the difference between a neutron number and its constituency.

• Mass- Mass is presented in Kilograms or meters. It refers the property of any physical body and its resistance to change in the state of motion when a specific amount of force is applied.

Conclusion

Just to be clear, the molar mass is a bulk property of a substance and not its atomic property. The molar weight of a substance is an intensive property. This means that it does not change with the size of the substance or sample. The molar mass can also be used to convert the mass of a substance to the mole and the other way around.

The printing world is quickly evolving into a revolutionary industry that serves several customers on the market. That is why most of the customers are inclined towards investing in modern printing techniques. Today, there are different types of printers and printing systems. For instance, there are LCD vs. DLP printing, which seems to be taking over the sector. So in this blog post, we strive to explain the nature of these two types of printing ideas. We focus more on the differences and similarities as well. Let us begin with our focus on LCD-002R, shall we?

Photocentric printing is also known as LCD 3d printing. Then there is the DLP printing, which seems to be giving the later a run for its money. Before we dwell into the main differences, let us define resin 3D printing. We should also discuss how DLP as well as LCD function. 

Resin 3D printing refers to a tech device and formula that applies 3D printers via stereolithography, especially when it comes to significant light processing. The idea is becoming more popular and has gained traction on the market. Resin-based printing is more affordable compared to other forms of printing. DPL printers are also becoming common. Therefore, prosumer-level options such as the Prusa coupled with SL1, are on the market to help serve the people too. 

The resin 3D printing, which is also identified as the vat polymerization, has three main categories: they include:

• LCD – The LCD printer refers to a primary common type of printer. It resembles a laser printer in many ways. But rather than using the laser to create the image, in LCD printing, you will realize that the printer shines a viable light via a crystal panel. The panel, in this case, it allows or blocks light from passing. That way, an image filled with dots will be formed. At the same time, the liquid crystal printer plays an integral part in producing high-quality printed materials.
• DLP-As the name suggests, DLP printing refers to a projector that helps in creating a viable image of different layers. This is usually acquired by shinning a direct light into the base of the resin. The DLP projector needs to regularly expand from a very minute source in order to cover a vast and significant area altogether. 

To picture this effect and impact, you need to think of the image of a photo you may have taken on the smartphone. And then imagine yourself zooming into the image. Check its sharpness as it declines.  It is critical for you as a prospect user to remember that distortion can be corrected for different professional devices. But this does not really mean that DLP printing is usually of poor quality.

Take-Home

The DLP printing machine is more than just a primary device. It can help its users in making calls, sending emails, as well as playing the music. You should also be in a position to take pictures using this device. If you are still wondering whether it is the right investment to make, then wonder no more because, from the look of things, it is.
