保留指数自动计算程序在油品单体烃毛细管气相色谱定性分析中的应用

The Application of Auto-Calculating Program for Retention Index in Qualitative Analysis of Monomel Hydrocarbon of Oil Products on CGC

本文在日本岛津系列色谱数据处理仪上用 BASIC 语言编制了线性程序升温保留指数和恒温保留指数的自动计算程序,并描述了程序的数学模型。本程序在开发色谱数据处理仪功能的基础上。利用色谱数据处理仪所贮存的色谱峰的保留时间自动进行保留指数的计算,从而避免了大量数据的重复输入,极大地缩短了计算时间和强度。因此,具有较强的实用性和方便性,以石油二厂常顶直馏汽油(初馏点～163℃)为例,使用该程序计算了每一组分的保留指数,用线性程序升温保留指数(I_(pt))值,纯物质等手段定性了约150个组分。

Auto-calculating BASIC program for linear heating program retention index and kovats retention index has been performed on chromatographic (AHIMADZU, Japan).Data processor and the mathematic model of the program has been described. Based on developing the function of the data processor the program can calculate the re- tention indexes automatically by using the retention time of the peaks stored on the data processor so the repeated input of a large amount of data has been avoided.The calculating time has been reduced extremely.Thus the program is practical and convenient. Take the overhead naphtha of atmoapheric column (inital boiling point～163℃) of No.2 refinery for example,the retention indexes of every components are calculated by this program.So far about 150 components are identified by means of the values of linear heating program retention index (I_(pt)) and pure substances.
