Questions about Reference substances & reagents (other)

What does "reagent according to Ph. Eur." on a bottle mean?

It means the reagent meets the specification in the reagents chapter of the European Pharmacopoeia, so it can be used in pharmacopoeial methods. The Pharmacopoeia is a Council of Europe text that EU medicines legislation makes binding. Such a reagent is not the same as a certified reference material. For assays and calibration, use a reference standard with its own certificate instead. See pharmacopoeia reagents and excipients and analytical standards and reference materials. For a quote or a second opinion, write to sales@luminixhealth.com.

When do I use a primary standard such as potassium hydrogen phthalate?

A primary standard is very pure and stable, so you can weigh it accurately and use it to determine the exact concentration of a volumetric standard, for example sodium hydroxide for titration. Dry it as the method describes and weigh precisely on a suitable balance. Store the standard dry in a well-closed container. Repeat the standardisation at regular intervals. See volumetric standard solutions and titrators and electrochemistry systems. Questions about a specific product? Contact sales@luminixhealth.com.

Why Reference substances & reagents (other)?

A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.

A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
