加压液体萃取技术在生物样品分析中的应用

Application of Pressurized Liquid Extraction in the Analysis of Biological Materials

改进生物样品的前处理技术,可以提高分析速度,改善分析效果,使被分析物快速、有效的检出.加压液体萃取技术(PLE)是采用高温高压进行样品分离的前处理技术,具有省时省溶剂、自动化的优点.本文就PLE在生物样品分析中的应用进行了评述.包括与其他萃取技术的比较、去除脂肪的方法和应用实例.

The development of sample preparation technique can improve the analytical speed and the separate effect. Pressurized Liquid Extraction （PLE） is an innovative sample preparation technique that combines elevated temperatures and pressures with liquid solvents to achieve fast and efficient removal of analytes of interest from various matrices. This paper reviewed the application in the analysis of biological sample. It included the comparison with other extraction techniques, the methods of defatting and the examples of application.
