Description General description Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Application L-Glutamic acid may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by ion chromatography technique. These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements. Biochem/physiol Actions An excitatory amino acid neurotransmitter that is an agonist at all subtypes of glutamate receptors (metabotropic, kainate, NMDA, and AMPA). Analysis Note These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available. Other Notes This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis. Footnote To see an example of a Certificate of Analysis for this material enter LRAA7158 in the slot below.
