Allure® AK Guard Cartridge
Chromatographic Properties
This highly retentive, highly selective phase—unique to Restek—was developed specifically
for the analysis of aldehydes and ketones as DNPH derivatives. Allure® AK is a reversed-phase
HPLC material that has the unique ability to separate all 13 carbonyl compounds specified
in California Air Resources Board (CARB) Method #1004 using a simple acetonitrile/water
gradient. Other columns require long analysis times or the use of tetrahydrofuran.
