Tenax-TA sampling tube enrichment
Tenax-TA sampling tube enrichment Details:

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a method for the determination of trace phenolic compounds in the air by gas chromatography-mass spectrometry with Tenax sampling tube. The Tenax sampling tube is used to adsorb trace phenolic compounds in the ambient air, and methanol is used for leaching. Wash and desorb phenolic compounds, add naphthalene-D8 as an internal standard in the eluent, use gas chromatography-selected ion monitoring mass spectrometry (GC-MS/SIM) for detection, and quantify by internal standard method. This method is qualitatively and quantitatively accurate, and has a good linear response. , The linear correlation coefficients of the regression curves are all greater than 0.999, the average recovery rate is 92.4% to 102%, the measurement interference is small, the detection sensitivity is high, and the minimum detection concentration in the air can reach 0.001 mg/m3 by sampling 10 L. Sample determination can fully meet the requirements for monitoring trace phenolic compounds in ambient air.

Tenax TA is a porous polymer with a chemical name of poly 2,6-diphenyl-p-phenylene ether. It has high thermal stability, oxidation resistance, strong moisture resistance, stable chemical properties, easy regeneration, and reusable . At present, Tenax TA is mainly used in the sampling and enrichment of volatile and semi-volatile organic compounds. The U.S. Environmental Protection Agency (EPA) stipulates that the Tenax TA adsorption tube sampling method is the standard sampling method for volatile and semi-volatile organic compounds.
