島津Porapak Q甲烷柱
島津Porapak Q甲烷柱 詳細(xì)信息：

名稱：甲烷柱
固定相：高分子小球
粒度：60-80目
型號(hào)：PQ
規(guī)格：2m*1/8
應(yīng)用：環(huán)境空氣/固定污染源廢氣/甲烷，總烴，非甲烷總烴的測(cè)定
適用于：安捷倫，賽默飛，瓦里安，布魯克，PE，島津

隨著經(jīng)濟(jì)社會(huì)的發(fā)展,不斷擴(kuò)大的工業(yè)生產(chǎn)向空氣中排放著大量污染物,這就需要準(zhǔn)確的檢測(cè)數(shù)據(jù)以實(shí)現(xiàn)有效的環(huán)境管理.氣相色譜法檢測(cè)廢氣中的甲烷,非甲烷總烴,應(yīng)用甲烷作為標(biāo)準(zhǔn)參考?xì)怏w較為合適,與丙烷比較,對(duì)非甲烷總烴的定量沒有較大差別,且時(shí)間上明顯縮短,提升了作業(yè)效率;在儀器配置上,浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司建議采用雙柱配置的氣相色譜,一次進(jìn)樣做完所有分析,效率更高,而且能夠有效提高實(shí)驗(yàn)結(jié)果的準(zhǔn)確性;手工配制方法盡管有些麻煩,但也能較好的滿足實(shí)驗(yàn)要求,且成本更低;與毛細(xì)管柱相比來說,填充柱的檢出限盡管稍差,但成本更低,已經(jīng)能夠滿足實(shí)驗(yàn)要求;在樣品采集環(huán)節(jié),污染源具有負(fù)壓時(shí),需要選用動(dòng)力采樣,而其余情況以及無組織排放,采用玻璃注射器采集,再注入惰性氣袋存放即可,這樣不但提高了采集效率,而且更加方便運(yùn)送,氣密性也很好,方便保存.

With the development of economy and society, the expanding industrial production emits a large amount of pollutants into the air, which requires accurate detection data to achieve effective environmental management. Gas chromatography is used to detect methane and non-methane total hydrocarbons in exhaust gas. Methane is more suitable as a standard reference gas. Compared with propane, there is no significant difference in the quantification of non-methane total hydrocarbons, and the time is significantly shortened, which improves the operation efficiency; in terms of instrument configuration, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. It is recommended to use a gas chromatograph with a dual-column configuration to complete all analyses in one injection, which is more efficient and can effectively improve the accuracy of the experimental results; although the manual preparation method is somewhat troublesome, it can also better meet the experimental requirements, and the cost Compared with the capillary column, the detection limit of the packed column is slightly worse, but the cost is lower, and it can already meet the experimental requirements; in the sample collection process, when the pollution source has negative pressure, it is necessary to use dynamic sampling, while the other It can not only improve the collection efficiency, but also more convenient for transportation, and the air tightness is also very good, which is convenient for storage.
