Avantor offers a wide range of certified organic standards designed for instrument calibration in ion-exchange chromatography (IC) applications, which can be applied toward environmental or food analysis and quality control. IC is an analytical technique used for the separation and quantification of anions and cations in aqueous samples. Avantor offers high-purity, well-defined reference materials ideal for low-ppm level quantification or trace analysis. Bottles of organic standards are available for a range of elements.

Organic reference standards, cyclazadone (NMIA D914), Certified Reference Material (CRM)

Supplier: LGC Standards PROMOCHEM

The purity value obtained from a combination of traditional analytical techniques is 99,6 ± 1,4% mass fraction, (95% coverage interval). The purity estimate by traditional analytical techniques was obtained by subtraction from 100% of total impurities by GC-FID, thermogravimetric analysis, Karl Fischer analysis and 1H NMR and also supported by elemental microanalysis.
