LpDNPH H Series Cartridges

Descrição detalhada : LpDNPH H Series Cartridges (H10) are air sampling devices, which are designed for sampling carbonyls in ambient, indoor, workplace, and source atmospheres. The unique solid phase extraction configuration of an LpDNPH cartridge makes the cartridge easy to use in the field as well as in the laboratory. Carbonyls are trapped on a 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 in acetonitrile and analyzed by HPLC. The built-in reservoir eliminates the need to attach a syringe to the cartridge for sample extraction/elution. Reusable adapters are available to connect the cartridge to the sampling pump., The H series of LpDNPH cartridges contain higher loadings of 2,4-DNPH and/or larger bed weights compared the S10 series and Rezorian cartridges. This provides a higher capacity for carbonyls making the H series cartridges the preferred choice for use in high concentration environments. The H series is available in 3 sizes: H10 (350 mg), H30 (1 g) and H300 (10 g) cartridges.
