高效微萃取技术与敞开式离子化质谱联用实现快速分析

摘要

Microextraction coupled to AMS showed greatpotential for the fast analysis of volatile organiccompounds;For limited targets，this setup can simplify theanalytical procedure and improve throughput，without chromatography separation;Of cause，Chromatographic separation isnecessary for many targets in complex samples;The development of new materials with twofunctions(selective enrichment and ionizationenhancement)could be an interesting area.Effect of pH value(A)，salt concentration(B)，organic solvent content（c）of sample solution on extraction efficiency;and the equilibriumextraction time profile of triazines for“Dip-it”PMME(D).
