Customer Information:
LpDNPH cartridges are air-sampling media devices designated for sampling carbonyls (like formaldehyde) in ambient, indoor and industrial hygiene atmospheres.
Carbonyls are trapped on a sampling cartridge containing high purity silica adsorbent coated with 2,4-dinitrophenylhydrazine (2,4-DNPH), where they are converted to the hydrazone derivatives. The derivatives are eluted from the cartridge with acetonitrile and analyzed by HPLC. Our LpDNPH cartridges meets NIOSH, OSHA, EPA, and ASTM specifications.
LpDNPH cartridge benefits:
Every lot of LpDNPH is tested for background contamination, an actual COA is included in the box, not a “representative” QA test
Our purpose is to solve the toughest problems in life science by collaborating with the global scientific community – and through that, we aim to accelerate access to better health for people everywhere.
