LC Performance Test Mix (5 components)
• Highly effective for characterizing LC column parameters.
• Simple, easy, reliable approach to quality control (QC)
evaluations or column classification.
• Monitor column performance over time.
The National Institute of Standards and Technology (NIST) has
formulated a mixture that is highly effective for characterizing
LC columns for efficiency, void volume, methylene selectivity,
retentiveness, and activity toward chelators and organic bases.
Results can be used for column classification, for column se-
lection, for monitoring column performance over time, or
for quality control. We test our material against the NIST 870
standard.
Dry components in 4 mL screw-cap vial. Reconstitute in 1 mL acetonitrile:water (75:25) to 2.1,
2.0, 4.4, 4.5, 4.0 mg/mL, respectively.

Carbohydrate LC Performance Check Mix (5 components)
Performance qualification (PQ) determines the precision of the
LC system. Our performance check mix for LC-RI consists of
five simple sugars in varied concentrations. We prepare the ref-
erence material in water, dehydrate it, and package it dry for
enhanced stability.
LC OQ Linearity Test Mix Kit
Linear detector responses to concentration variations are an
important part of operation qualification (OQ) for LC instru-
ments. Our kit of five aqueous solutions of caffeine can be used
to generate simple plots of UV response versus concentration.
Certificate of analysis includes caffeine concentration, calcu-
lated variance in preparing each mixture, a linearity plot, and
coefficient of determination (r²) for the linear plot.
Contains 1 mL each of these mixtures.
