【摘要】 本工作以无分流方式进样,对低碳到高碳(C₁—C₁₁)的碳氢化合物进行色谱分析,然后用色谱-质谱-微机联用进行定性、定量分析、采用本法从燕山大气样品中鉴定出45种化合物,其特点是省时,灵敏度较高。更多还原

【Abstract】 A method was developed for simultaneous analysis of low and high hydrocarbons in the atmosphers by means of spiltless injection technique and capillary column GC/MS/Computer. Using this method, about 100 chromatogiaphic peaks, of which 45 being identified, were obtained from the atomspheric samples taken from Yanshan petrochemical district of Beijing.更多还原
