An automated on-line method is described that involves a first LC separation on a large column, evaporation of a 6-ml fraction in an on-line solvent evaporator, a second LC separation using a different mobile phase, fractionating the components of interest and transfer to GC through the in-line vaporizer/overflow interface. The method is designed for the injection of a large amount of food extract (e.g. up to 200 mg of fat) and is applied to the analysis of mineral oil material in a linseed oil.
本文描述了一种自动化在线方法，该方法包括在大柱上进行第一次液相色谱分离，在在线溶剂蒸发器中蒸发6毫升馏分，使用不同流动相进行第二次液相色谱分离，分馏感兴趣的组分并通过在线蒸发器/溢流接口转移至气相色谱仪。该方法设计用于进样大量食品提取物（例如高达200毫克脂肪），并应用于亚麻籽油中矿物油物质的分析。
