測定室內空氣中苯系物
測定室內空氣中苯系物 詳細信息：
Tenax-TA 應用領域：GC用填料和吸附劑，主要分析水、土壤、 大氣、呼吸氣、香精香料和室內空氣的高沸點化合物，如醇、酚、胺、醛、酮和鹵代芳烴等。
浩瀚色譜（山東）應用技術開發有限公司建立用熱脫附-氣相色譜/質譜聯用法(ATD-GC/MS)測定室內空氣中苯系物的分析方法。
[方法]采用TenaxTA吸附-二次熱解吸-毛細管氣相色譜/質譜法定量,研究確定了采樣方法、解吸條件和分析條件。
[結果]實驗表明苯、甲苯、乙苯、間(對)二甲苯、苯乙烯和鄰二甲苯的吸附效率均在97%以上,解吸效率均在99%以上,其相對標準偏差小于10%,回收率在96.8%～104.8%之間,線性相關系數在0.9993～0.9997之間,對應的低檢出濃度分別為0.0001、0.0007、0.0005、0.0005、0.0005、0.0007mg/m~3。
[結論]本方法適合測定室內空氣中低濃度的苯系物。

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
