1/4*3.5 Tenax-TA采样管富集的详细资料

Tenax-TA采样管富集
Tenax-TA采样管富集 详细信息：

浩瀚色谱（山东）应用技术开发有限公司建立了Tenax采样管富集气相色谱-质谱测定空气中痕量酚类化合物的方法.用Tenax采样管吸附环境空气中的痕量酚类化合物,用甲醇淋洗解吸酚类化合物,洗脱液加入萘-D8作为内标,利用气相色谱-选择离子监测质谱(GC-MS/SIM)进行检测,内标法定量.该方法定性、定量准确,线性响应良好,回归曲线的线性相关系数均大于0.999,平均回收率为92.4% ～102% ,测定干扰小,检测灵敏度高,按采样10 L计算,空气中低检测浓度可达0.001 mg/m3.用于实际样品测定,完全能满足环境空气中痕量酚类化合物监测的要求.

Tenax TA是一种多孔的高分子聚合物,化学名为聚2,6一二苯基对苯醚,它热稳定性高,耐氧化,抗湿性强,化学性质稳定,易再生,可重复使用。现在Tenax TA主要应用于挥发性和半挥发性有机物的采样和富集等方面,美国环保总署(EPA)规定Tenax TA吸附管采样法为挥发性和半挥发性有机物的标准采样方法。

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.
