产品说明

一般描述

LpDNPH H Series Cartridges (H30) are air sampling devices and its unique solid phase extraction configuration makes the cartridge easy to use in the field as well as in the laboratory. It is designed for sampling carbonyls in ambient, indoor, workplace, and source atmospheres. 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.
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。

特点和优势

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.
