【摘要】 <正> 自从1968年Verzele等提出了玻璃毛细管柱的静态涂渍方法以来,尽管此种方法的涂渍速度比动态法慢得多,但用这种方法涂渍液膜厚度可人为控制,因此到目前为止静态法仍被广泛地应用着。 1983年Kong等首先提出了在提高温度下静态涂渍的方法。并发现当用二氯甲烷和戊烷混合溶剂时,蒸发速度比用纯二氯更多还原

【Abstract】 A systematic study has been carried out to optimize the solvents to be used for static coating of various stationary phases at 75℃. It has been found that for each stationary phase, there existed a certain optimal composition for a binary mixture, which could give the fastest coating speed for the stationary phase liquid solution. In regard to OV-101 and PEG 20M the most suitable binary solvents are 1:1 (v/v) of n-pentane and acetone, and 1: 1 (v/v) n-pentane aad methylene chloride, respectively.更多还原
