Description générale

Our innovative BPE-DNPH cartridge is a dual-bed cartridge device designed for sampling of carbonyls in ambient, indoor and industrial atmospheres. Like traditional DNPH sampling devices, carbonyls (e.g. formaldehyde) are trapped onto our high purity 2,4-dinitrophenylhydrazine (LpDNPH) coated silica gel adsorbent and are converted to form stable hydrazone derivatives but offers the advantage of a 1,2-bis(2-pyridyl) ethylene (BPE) silica gel bed in front resulting in a built-in ozone scrubber that is not affected by high humidity or rainy conditions.

It is a well-known problem when sampling airborne carbonyls using DNPH-coated silica gel devices that ozone interferes with their analysis. To remove this ozone interference, traditional ozone scrubbing devices containing 1.5 g of Potassium Iodide (KI) are used in front of the DNPH device to trap the ozone, which causes negative ozone interference. In high humidity environments and rainy conditions, potassium iodide cartridges (or other multiple bed devices containing both potassium iodide and DNPH) result in sample loss, due to moisture condensation and collection inside the device.

Benefits:
  • Integrated ozone scrubber
  • No extra connections
  • No leaking cartridges
  • High Purity adsorbents for better accuracy in trace analysis
  • Low Background
  • Individual packaging in zip seal bag to maximize sample integrity
  • Suitable for NIOSH 2016, EPA TO-11A, EPA IP-6A and ASTM D5197
*Optional: Simultaneous measurement of ozone and carbonyls in one device

Application

BPE-DNPH Cartridge is used as a sampling device for the sampling of volatile organic compounds in surgical smoke samples analyzed by ultra-performance liquid chromatography technique.
