Why Clearsynth is the Ultimate Choice

At Clearsynth, we are dedicated to providing the highest quality Certified Reference Standards (CRS) to our clients in the pharmaceutical, biotech, and chemical industries. Our CRS products are well-characterized, highly purified, and traceable to national and international metrology institutes. Here, we will discuss the importance of CRS, why you should choose Clearsynth for your reference standard needs, and some additional applications and usage of CRS.

What are Certified Reference Standards?

Certified Reference Standards are compounds that are used as a reference for analytical testing. They are essential in ensuring the accuracy, precision, and reliability of analytical results. CRS are highly purified, well-characterized compounds, and are the highest level of reference standard, traceable to national or international metrology institutes.

Why are Certified Reference Standards important?

The quality and reliability of analytical results depend on the accuracy and consistency of reference standards. Inaccurate or unreliable reference standards can lead to erroneous results, which can have serious consequences in the pharmaceutical, biotech, or chemical industry. Therefore, it is crucial to choose a reliable source for your reference standards.
