Study on the Determination Method of Non-hydrocarbon Components of LPG
Select the suitable gasification conditions,an injection sample system,two six-way valves,three chromatogra-phy analysis columns and two FID detector gas chromatography systems.Optimizing the chromatographic conditions,samsample into the column MC-1,when the hydrocarbon components of C1 to C5 but not hydrocarbon oxides,select the appropriate valve switching time,introduce the nonhydrocarbon oxides into the chromatographic column MC2.The two classes of components are effectively and completely separated and entered into the corresponding FID detector for analysis.That is a good injection of hydrocarbons and non-hydrocarbon oxides within 30 min.The external standard method was es-tablished to quantify the content of non-hydrocarbon oxides.
