交联聚苯乙烯

Chromosorb-103: 强极性, 白色, 堆密度0.32g/mL, 比表面积15-25m2/g, 高使用温度275℃, 分析C1-C6胺类, 醇, 醛, 酮.

空气中丁胺采集在碱性多孔微球硅胶上，用０.１ｍｏｌ／ＬＨ２ＳＯ４解吸，０.３ｍｏｌ／ＬＫＯＨ碱化后，经Ｃｈｒｏｍｏｓｏｒｂ１０３柱分离，ＦＩＤ检测器气相色谱法测定，保留时间定性，峰高定量。结果表明，检测限０３μｇ／ｍｌ，低检出浓度０３ｍｇ／ｍ３（采集４Ｌ空气）批内精密度１８％～４６％，批间精密度２０％～３１％，平均解吸效率９４９％，样品室温下可保存２周。

Crosslinked polystyrene

Chromosorb-103: strong polarity, white, bulk density 0.32g/mL, specific surface area 15-25m2/g, maximum use temperature 275℃, analysis of C1-C6 amines, alcohols, aldehydes, ketones.



The butylamine in the air was collected on alkaline porous microsphere silica gel, desorbed with 0.1mol/LH2SO4, and alkalized with 0.3mol/LKOH, separated by Chromosorb 103 column, determined by gas chromatography with FID detector, retention time qualitative, peak height Quantitative. The results show that the detection limit is 0.3μg/ml, the lowest detection concentration is 0.3mg/m3 (collecting 4L air). The intra-assay precision is 1.8%～46%, and the inter-assay precision is 2.0%～3 1%, the average desorption efficiency is 94.9%, and the samples can be stored for 2 weeks at room temperature.
