Speciality phases

Polar sorbent coated with 2,4-dinitrophenylhrdrazine (2,4-DNPH)

BEKOlut® DNPH

Carbonyl compounds react within the DNPH cartridge to form immobilized hydrazones which can be eluted and analyzed by HPLC.
Determination of formaldehyde

Typical Application: Atmospheric aldehydes and ketones are trapped by reacting with the DNPH in the cartridge to form stable hydrazone.
