高效微萃取技术与敞开式离子化质谱联用实现快速分析

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).
