Calibration Standards & Test Mixtures

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

Pickering’s Calibration Standards have a reputation worldwide for quality and reliability in all post-column systems and methods. Additionally, we now offer Carbamates Calibration Standards and Internal Standard suitable for EPA 531.1 and EPA 531.2 analysis. Eight Amino Acid Standard mixtures are available for a variety of applications. The standards are in packs of 5 1mL ampoules.

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.
