Unlabeled Reference Standards


Standards are materials containing a precisely known concentration of a substance for use in quantitative analysis in assays of drug substances and formulations, blood analyses, limit tests, or controls. A standard can also provide a reference that can be used to calibrate analytical instruments as in identification tests, system suitability tests, or chromatographic peak markers.

The standards listed below are not labeled in any position. They are used for multiple avenues of focus such as environmental standards, in-born errors, pharmaceutical reference standards, unlabeled reference standards and impurities reference standards.
