haohan磐诺A90系列使用硅烷化玻璃微球总烃柱2m*4mm

浩瀚色谱（山东）应用技术开发有限公司以HJ/T 38-1999为基础,针对气相色谱法测定污染源废气中非甲烷总烃存在的诸多问题进行探讨,在总烃出峰峰形、废气氧峰值测定、高沸点物质干扰等方面做了研究试验。结果表明,1ml定量环容易造成总烃出现平头峰,改成0.25ml定量环能得到好的峰形;非甲烷总烃的检出限为0.04 mg/m~3(以碳计);氧峰值与氧量具有线性关系,应根据氧量判断氧峰值大小,而不是统一扣除除烃空气氧峰值;废气中存在高沸点组分时,容易吸附于采样容器内壁,将样品加热至100℃再测试可提高该组分的检出率。

名称：硅烷化玻璃微球总烃柱

适用于磐诺，福立，天美，东西，北分瑞利，华爱，安捷伦，岛津，赛默飞，瓦里安，布鲁克，PE Based on HJ/T 38-1999, Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. discussed many problems existing in the determination of non methane total hydrocarbons in waste gas of pollution sources by gas chromatography, and conducted research and tests on the peak shape of total hydrocarbons, determination of oxygen peak in waste gas, interference of substances with high boiling point, etc. The results show that 1ml quantitative ring is easy to cause flat peak of total hydrocarbon, and it can get good peak shape by changing to 0.25ml quantitative ring; The detection limit of non methane hydrocarbon is 0.04 mg/m3 (calculated by carbon); There is a linear relationship between the oxygen peak value and the oxygen content. The oxygen peak value should be judged according to the oxygen content, instead of uniformly deducting the peak value of hydrocarbon removal air oxygen; When there is a high boiling point component in the exhaust gas, it is easy to be adsorbed on the inner wall of the sampling container. Heating the sample to 100 ℃ and then testing can improve the detection rate of this component.
