HPLC OQ Linearity Test Mix Kit
Linear detector responses to concentration variations are an
important part of operation qualification (OQ) for HPLC
instruments. Our kit of five aqueous solutions of caffeine can be
used to generate simple plots of UV response versus concentra-
tion. Certificate of Analysis includes caffeine concentration, cal-
culated variance in preparing each mixture, a linearity plot, and
coefficient of determination (r²) for the linear plot.

Carbohydrate HPLC Performance Check Mix
(5 components)
Performance qualification (PQ) determines the precision of the
HPLC system. Our performance check mix for HPLC/RI consists
of five simple sugars in varied concentrations. We prepare the
reference material in water, lyophilize it, and pack it dry for
enhanced stability.
Dry components in 4mL screw-cap vial. Reconstitute in 1mL acetonitrile:water (75:25)
to 2.0, 2.1, 4.4, 4.5, 4.0mg/mL, respectively.

HPLC Performance Test Mix
(5 components)
The National Institute of Standards and Technology (NIST) has
formulated a mixture that is highly effective for characterizing
HPLC columns for efficiency, void volume, methylene selectivity,
retentiveness, and activity toward chelators and organic bases.
Results can be used for column classification, for column selec-
tion, for monitoring column performance over time, or for qual-
ity control. We test our material against the NIST 870 standard.
