General description

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.
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.

Features and Benefits

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.
