Calibration Standards & Test Mixtures

Overview

img-generic2Calibration Standards & Test Mixtures

      • Quantitative and guaranteed
      • Each lot tested chromatographically
      • Chromatographically-pure starting components

Pickering's Amino Acid Standards have a reputation worldwide for quality and reliability in all post-column systems and methods. Six Amino Acid Standard mixtures are available for a variety of applications. The standards are in 5 mL vials in an appropriate citrate buffer.

Although they are stored frozen at the factory, Pickering's calibration standards remain stable when shipped at ambient temperatures. Upon receipt, however, it is important to place them into a freezer immediately, and store until ready for use.

Test Mixtures are qualitative standards and intended to be used to establish an elution profile and for troubleshooting.
