SORBENT TUBE DNPH Active Sorbent Tube Active Sorbent Tube for Aldehydes DNPH Passive Sorbent Tube DNPH Passive Sorbent Tube for Aldehydes

DNPH Active Sorbent Tube Active Sorbent Tube for Aldehydes It is ideal for active sampling of aldehydes/ketones in the sorbent tube filled with - DNPH (2,4 - dinitrophenylhydrazine) impregnated silica gel. High-accuracy sampling is available, because Sibata items are so produced as to make low blank value, and the small variation by lot-to-lot, and that in the same lot as well. Sampling Extraction HPLC Analysis To connect tube to a mini-pump, Push the solvent with the syringe barrel, To analyze with High Performance and suck at a constant flow rate and extract the trapped substance. Liquid Chromatography(HPLC) DNPH Active Sorbent Tube Ozone Scrubber samling pump ■Related Product 【Ozone Scrubber】 Ozone scrubber is a cartridge for removing ozone in the atmosphere. You can remove the ozone by potassium iodide filled in the cartridge. The ozone will decompose the DNPH derivative. Please use it when you use the DNPH Active Sorbent Tube in an environment such as an outdoor where ozone exists. ■Specifications Name DNPH Active Sorbent Tube Ozone Scrubber Trapping Substance Aldehydes ,Ketones － Adsorbent DNPH (2,4 - dinitrophenylhydrazine) impregnated silica gel (350mg)DNPH impregnated amount: about 1mg Potassium iodide Dimension 43mm ×φ16mm　 Diameter of suction extraoral: about φ4mm and φ6mm（two stages） Transportation/Storage Refrigerated transport/Chilled storage － Expiration date Within one year after production (it is shown on the bag.)

DNPH Passive Sorbent Tube DNPH Passive Sorbent Tube for Aldehydes It is a passive sampler filled with DNPH impregnated silica gel in the diffusion tube. It is ideal for sampling formaldehyde, acetaldehyde at low blank. You can connect the tube directly to a syringe at the time of analysis, and the structure is so designed as allows for easy operation with less extraction loss. Sampling Extraction HPLC Analysis Left for 24 hours by setting the holder, Push the solvent with the syringe barrel, You can make injection without pretreatment with after it is removed from the bag. and extract the trapped substance.
