使用 Tenax-TA 填料的典型分析流程如下：
采样： 使用装有 Tenax-TA 填料的吸附管，以恒定流速抽取一定体积的气体样品。目标有机物被保留在填料上。
运输与储存： 采样后，将吸附管两端密封，可运回实验室进行分析。Tenax-TA 的稳定性保证了样品在储存期间不易发生变化。
热脱附： 将吸附管放入热脱附仪中，快速加热（通常到 250-300°C），同时用载气反吹。被吸附的化合物被热解吸出来。
聚焦与进样： 脱附出来的化合物被冷阱（低温聚焦器）再次捕集，然后快速加热冷阱，以狭窄的带状脉冲形式将样品注入气相色谱柱。
GC-MS 分析： 在色谱柱中进行分离，最后由质谱检测器进行定性和定量分析。
Tenax-TA 对非极性和弱极性的挥发性有机物（VOCs） 和半挥发性有机物（SVOCs） 有很强的吸附能力，特别是对于芳香烃、卤代烃、酮类、酯类等化合物。
它对永久气体（如氧气、氮气、二氧化碳）和极低沸点的化合物（如甲烷、乙烷）吸附很弱

The typical analysis process for using Tenax TA filler is as follows:
Sampling: Use an adsorption tube filled with Tenax TA packing to extract a certain volume of gas sample at a constant flow rate. The target organic compound is retained on the filler.
Transportation and storage: After sampling, seal both ends of the adsorption tube and transport it back to the laboratory for analysis. The stability of Tenax TA ensures that the sample is not easily changed during storage.
Thermal desorption: Place the adsorption tube into a thermal desorption apparatus, rapidly heat it (usually to 250-300 ° C), and blow back with a carrier gas. The adsorbed compounds are thermally desorbed.
Focusing and injection: The desorbed compound is captured again by a cold trap (low-temperature focusing device), and then the cold trap is rapidly heated to inject the sample into a gas chromatography column in the form of narrow band pulses.
GC-MS analysis: Separation is performed in a chromatographic column, followed by qualitative and quantitative analysis using a mass spectrometer detector.
Tenax TA has strong adsorption capacity for non-polar and weakly polar volatile organic compounds (VOCs) and semi volatile organic compounds (SVOCs), especially for aromatic hydrocarbons, halogenated hydrocarbons, ketones, esters, and other compounds.
It has weak adsorption for permanent gases (such as oxygen, nitrogen, carbon dioxide) and extremely low boiling compounds (such as methane, ethane)
