| Abstract: | The silica gel tube strongly adsorbs polar compounds ethylbenzene,styrene and hydrogen fluoride.The 1-meter-long silica gel tube collects the above samples,and the recovery rates are only 60%,54.7%and 58.9%.The PA tube(nylon tube)can react with hydrogen fluoride,and the recovery rate is only 7.1%.The PTFE tube(Teflon)has good inertness and recovery rates to collect various gases.The gas path system and sample cell of the Handy Fourier Transform Infrared Spectrometer have strong adsorption of hydrogen fluoride and hydrogen chloride,and it takes longer to acquire accurate results. |
