测空气和废气中甲醇时气相色谱法的改进

空气和废气监测分析方法一书第五章中甲醇的气相色谱分析方法,应该解决采样时间长回收效率低和色谱分离存在在拖尾大水峰三个方面的问题。

Improvement in The Method of Analyzing Methanol in Atmosphere and Waste Gas by Gas Chromatogrphy

There is the book named "the method of detecting and analysizing atmosphere and waste air", in which the method of carbinol gas chrmatography analysis involved in chapter five can solve three problems about long-term process of sampling, low recycle officiency and the existance of "bigwarter peak of drawing tail"in chromatography seperation. We use the macromolecule polymer GDX102, glass poles of 2 meter and FID detectors injected with1 ml gas smle in experiments The minimum detective conctentration is 0.08mg/m3, so the chromatography analysis method of using water solution to absorbthe carbinol can be completely substitude for this kind of new method. During the process of analysingweter sample and gas sample by using GDX102 poles.carbinol and ethanol exist high seperated officiency and can't produce thd phenmenon of "big water peak of drawing tail"the new method is possessed of thespecial characteristic such as timeasving samplig, efficient analysis,precise, exact and credible detective result.
