LpDNPH S10L Cartridge

Descrição detalhada : LpDNPH S10L Cartridge is basically used for sampling carbonyls (e.g., formaldehyde) in ambient, indoor, and industrial atmospheres. It works by trapping carbonyls on a high purity silica adsorbent coated with 2,4-dinitrophenylhydrazine, then converted to hydrazone derivatives. The derivatives are eluted from the cartridge in acetonitrile and are analyzed by HPLC., The S10L cartridges features a reversible design and is for analysts who prefer shorter dimensions and does not require an adaptor for sampling. The cartridge is eluted by connecting to a syringe barrel (empty SPE cartridge) that acts as a reservoir for gravity-fed elution solvent. Meets EPA TO-11A requirements.
