LpDNPH H Series Cartridges (H10) are air sampling devices used for sampling carbonyls via trapping them 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.
与 S10 系列和 Rezorian 小柱相比，该 LpDNPH H 系列小柱内含更多的 2,4-DNPH 涂渍量和/或填料量。这提供了更高的羰基化合物吸附容量，使 H 系列小柱成为高浓度样品环境的首选。H 系列有三种规格类型：H10 (350mg)、H30 (1g) 和 H300 (10g) 小柱。

LpDNPH cartridges feature:

• High purity adsorbent, for better accuracy in trace analysis.
• Low pressure drop, to enable use at high sampling rates (1.5-2 L/min.), even with personal sampling pumps.
• Individual packaging, to maximize sample integrity.
• Bar code labels, for fast and accurate sample identification.
