What Are The Standards Used For HPLC?

Standards are important in all analytical works, including High-Performance Liquid Chromatography (HPLC) as they help to establish the accuracy and precision of a test method. With the use of internationally recognized standard reference materials in your work, the results of the analysis can be accepted worldwide.

In general, there are 2 main groups of HPLC standards, Primary standards (a.k.a. certified reference materials) and Secondary standards (a.k.a. working standards). They are useful in identifying the unknown substance, quantifying the analytes or calibrating the accuracy and the precision of analytical measurement. Here, we’ll further explain the details of primary and secondary standards used in HPLC.

Primary Standard (Certified Reference Materials)

Primary standards are ultra-high purity grade materials that normally use in analyses like identification and purity test of a compound. The traceability for this standard is usually the highest, and meet the requirements needed by a national or international standards body.

Secondary Standard (Working Standard)

Secondary standards are also high purity grade materials. They have a lower price compared to the primary standard as the traceability is generally lower. Hence, they are usually put into routine use in laboratories.

What Are The HPLC Standards That We Can Supply?

We are supplying over 20,000 HPLC standards from Merck and Sigma-Aldrich, Cromadex, LGC Standards and Toronto Research Chemical Standards. These standards are manufactured to meet the standard ISO/IEC 17025, ISO Guide 34 and ISO 17034, which is the highest achievable quality level for reference material producers.
