This helps you accurately detect moisture in your raw materials and finished ingredients, ensuring your fine and specialty chemicals are effective and of the right specification when they reach your customers. 

The types of particles in your fine and specialty chemicals can affect product performance. For example, particle size and distribution can affect the finish of coatings in aerosols sprays such that these can produce an undesired matt or glossy appearance. Active pharmaceutical ingredients (APIs) are analyzed and tested in this regard to be within specifications to ensure performance, for example relating to their dissolution behavior, which can not only have an effect on processing the product but more importantly on the API’s efficacy in its final dosage form.

Inorganic impurities in fine and specialty chemicals can come from the environment or can be produced during the manufacturing process. You must sample your chemicals using a residue on ignition test, also known as a sulphated ash test, to determine the percentage of inorganic impurities. If the amount of these impurities is too high, they could affect the performance or quality of your specialty chemicals and where the chemicals are used in paints for example, they can affect your product’s safety profile.  

테스트 대상:

• Production reagents 

• 무기염류 

• Heavy metals such as lead, chromium and mercury

We have quality products including ashless filters and durable, easy-to-clean balances with simple to use software for residue on ignition applications which can generate reliable results with even small sample sizes. These help you reproducibly calculate the percentage of inorganic impurities in your specialty chemicals to ensure they are the right quality and safety specifications for your customer’s applications. 

You need to monitor the quality of the water that goes into manufacturing your fine and specialty chemicals, as well as the wastewater it produces. Fine and specialty chemicals often need processing or treatment with good quality water to remove impurities and many substances in your wastewater from chemical production can cause major damage to the environment if they enter water ways in high concentrations. 

테스트 대상:

• pH 

• 중금속류

We have durable, simple to use products including precise pipettes that can handle low volumes, specific filters, and robust pH meters to help you sample and analyze your process and wastewater to ensure it maintains its safety profile to meet industry guidelines time after time.​

Whether in starting materials or processed products, inappropriate levels of undesirable compounds in your fine and specialty chemicals can make them unstable and can affect performance. In some applications they can render chemicals unsafe, for example high levels of chromium in paints can cause toxicity problems. With reliable sample prep methods and accurate analytical tools, you can detect and monitor the levels of these compounds in your fine and specialty chemicals to ensure they meet your rigorous QA requirements for impurity testing. ​

Great samples start with pure water and we provide robust water purification systems for producing ultrapure water for buffer and sample preparation. We also offer pipettes, designed for accurate low volume sampling and precise balances with easy-to-use software. This combination of trusted sample preparation tools can be used in an integrated workflow to help you get accurate, traceable results from your analysis, and deliver stable, effective specialty chemicals. 

Sometimes your fine and specialty chemicals are used in a liquid form, so you must test their stability and performance in solution to ensure they meet quality specifications. For example, if a paint viscosity is too lower it can indicate possible contamination or degradation, all of which will affect your customer’s product performance. 

테스트 대상:

• 색상   

• pH  

• 점도 

We provide user-friendly, compact water purification systems for producing ultrapure water for high quality aqueous sample preparation where and when it is needed. We also offer pipettes for accurate low volume sampling and balances with software which is simple to use and generates reliable results. These trusted sample preparation tools help you rapidly produce the best solutions of your specialty chemicals for testing every time. 

Microbes in your process water can contaminate your fine and specialty chemicals making them unstable or perform poorly. For example, with paints biocides are used less frequently as consumers want safer products, but this means paints are more susceptible to microbial contamination which can cause paint bubbling or paint that produces unpleasant odors. To avoid these issues, process hygiene when producing fine and specialty chemicals for paints is more important than ever. To monitor your process water, you must undertake regular water tests and decontaminate your water systems if high levels of microbes are present. 

테스트 대상: 

• 총 호기성 미생물 수 (박테리아, 진균)

We have high-quality products including robust membrane filtration systems, as well as media and label-free biosensor technologies for safe and efficient detection of microorganisms in your process water. These enable you to generate accurate, reproducible results and help you meet industry standards with microbial testing of your specialty chemicals. ​

Microbial contamination can be present in your raw materials or could be introduced during production. Although microbes are often present in low numbers in many fine and specialty chemicals, if contaminated water is present in food additives or paints for example, this can lead to microbial contamination and product degradation. This type of contamination can shake your customer ‘s confidence in your brand and may have a financial impact on your company. Your fine and specialty chemicals are not expected to be microbe-free, but they must be within the limits defined for potential spoilage organisms. 

테스트 대상: 

• 총 호기성 미생물 수 (박테리아, 진균)
• Specific spoilage bacteria such as Flavobacterium
• Specific spoilage molds such as Penicillium

Adhering to a regular sampling plan with in-process controls along the entire production chain from raw materials through to finished chemicals you can easily detect unwanted microbes. Our products for microbial testing such as filters, pumps and manifolds can help capture the smallest microorganisms for analysis. We also provide media and label-free biosensor technologies for efficient, accurate detection of potential spoilage microorganisms to help you meet industry standards with your microbial limits testing.

Introducing microbes at any stage in your production, filling and packaging process may cause changes in viscosity in paints and coatings for example, as well as oxidation, and degradation leading to poor quality chemicals which may be unstable or ineffective for their application. Good process hygiene is essential, especially where your fine and specialty chemicals are going to be used as the basis for active pharmaceutical ingredients or food additives and part of that is knowing which microorganisms are in the air in your production, filling and packaging areas to minimize contamination risks.
