ChromatographicProperties:
This highly retentive, highly selective phase, unique toRestek,was developed specifically for
the analysis of aldehydes andketones asDNPHderivatives.Allure®AK is a reversedphase
HPLCmaterial that has theunique ability to separate all thirteen carbonyl compounds speci-
fied inCaliforniaAirResources Board (CARB)Method#1004, using a simple acetonitrile/
water gradient, in less than15minutes.Other columns require long analysis times or theuse
of tetrahydrofuran.
