HPLCOQLinearityTestMixKit
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 canbe
used to generate simple plots of UV response versus concentra-
tion. Certificate of Analysis includes caffeine concentration, cal-
culated variance inpreparing eachmixture, a linearity plot, and
coefficient of determination (r²) for the linear plot.

CarbohydrateHPLCPerformanceCheckMix
(5 components)
Performance qualification (PQ) determines the precision of the
HPLC system.Ourperformancecheckmix forHPLC/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.

HPLCPerformanceTestMix
(5 components)
TheNational Institute of Standards andTechnology (NIST) has
formulated a mixture that is highly effective for characterizing
HPLC columns for efficiency, voidvolume,methylene selectivity,
retentiveness, and activity toward chelators and organic bases.
Results can be used for column classification, for column selec-
tion, formonitoring columnperformanceover time,or forqual-
ity control.We test ourmaterial against theNIST870 standard.
