测定室内空气中苯系物
测定室内空气中苯系物 详细信息：
Tenax-TA 应用领域：GC用填料和吸附剂，主要分析水、土壤、 大气、呼吸气、香精香料和室内空气的高沸点化合物，如醇、酚、胺、醛、酮和卤代芳烃等。
浩瀚色谱（山东）应用技术开发有限公司建立用热脱附-气相色谱/质谱联用法(ATD-GC/MS)测定室内空气中苯系物的分析方法。
[方法]采用TenaxTA吸附-二次热解吸-毛细管气相色谱/质谱法定量,研究确定了采样方法、解吸条件和分析条件。
[结果]实验表明苯、甲苯、乙苯、间(对)二甲苯、苯乙烯和邻二甲苯的吸附效率均在97%以上,解吸效率均在99%以上,其相对标准偏差小于10%,回收率在96.8%～104.8%之间,线性相关系数在0.9993～0.9997之间,对应的低检出浓度分别为0.0001、0.0007、0.0005、0.0005、0.0005、0.0007mg/m~3。
[结论]本方法适合测定室内空气中低浓度的苯系物。

Determination of benzene series in indoor air Details:
Name: Adsorption tube
Specification: 1/4*3.5
Filler: 200mg
Shape: U, straight pipe
Model: TENAX-TA
Tenax-TA application areas: fillers and adsorbents for GC, mainly analyzing high-boiling compounds in water, soil, atmosphere, breathing gas, flavors and fragrances and indoor air, such as alcohols, phenols, amines, aldehydes, keto
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established an analytical method for the determination of benzene series in indoor air by thermal desorption-gas chromatography/mass spectrometry (ATD-GC/MS).
[Method] Using TenaxTA adsorption-seco
[Result] The experiment showed that the adsorption efficiency of benzene, toluene, ethylbenzene, m-(p-)xylene, styrene and o-xylene were all above 97%, the desorption efficiency was all above 99%, and the relative standard deviation was less than 10%. The recovery rate is between 96.8% and 104.8%, and the linear correlation coefficient is between 0.9993 and 0.9997. The correspo
[Conclusion] This method is suitable for the determination of low-co
