The adsorbent material is spherical silica-gels coated with 2,4-Dinitrophenylhydrazine, which is appropriate for the sampling of aldehyde and ketone. The particle size of the adsorbent material is 120 um and delivers better air permeability and higher sampling efficiency compared to irregular particle type silica-gels. In addition, the background is exceptionally low due to our rigorous quality control inspection tests. Potassium iodide is packed to the cartridge to remove ozone in air. It is known that ozone decomposes DNPH derivative and influences the analysis results. The above phenomenon can be prevented by installing this cartridge in front of the DNPH cartridge, providing highly reliable testing results.
