2、近年来也已大量应用;基质固相分散、凝胶渗透色谱、分散固相萃取等技术的应用,使净化效率大大提高。在样品分析中,传统的气相色谱、高效液相色谱特别是后者虽然仍在大量应用,但气相色谱-串联质谱、高效液相色谱-串联质谱技术由于具有极高的选择性和灵敏性,已得到迅速发展和广泛应用。酶联免疫吸附分析、胶束电动毛细管色谱、近红外光谱技术等分析检测技术的应用潜力很大。关键词:吡唑醚菌酯;残留;分析;色谱;质谱Developmentofmethodsforthedeterminationofpyraclostrobinresidue*YOUXiao,JINGLe-Gang(CollegeofLifeSciencea
