Optimized Linear Temperature Programming for Capillary Gas Chromatography by the Method of Gridding Search
网格搜索法优化毛细管气相色谱线性程序升温

Linear temperature programming of capillary gas chromatography was optimized by using a new method of gridding search A point of gridding demonstrated a condition of temperature programmed and the resolution and the retention time were optimized at all gridding points With a new design of calculation, the method not only considered directly all components that were separated, but the velocity of calculation was improved also Twenty one compounds of alkanes, alcohols, halo hydrocarbons and aromatic hydrocarbons, of which Kovats Indexes are varying from 600 to 1 000 , were separated by this new method on an OV 101 column under linear temperature programming. Good results were obtained The time for optimizing the 21 compounds was less than 1 min.
