甲基丙烯酸单体中对苯二酚的多离子定量测定法

Quantitative Determination of Hydroquinone in Methacrylic Acid by MIS

摘要: 本文采用硅醚化反应和添加内标的方法,在MAT44S GC/MS/DS质谱计上成功地测定了甲基丙烯酸及甲基丙烯酸甲酯单体中阻聚剂对苯二酚的含量。检测极限约为20毫微克/微升,相对误差小于10％。

Abstract: Hydroquinone,the polymerization inhibitor of methacrylic acid monomers,is quantitatively determined by GC/MS/MIS technique using BSFS derivativemethod and uaphthalene as inner standard with MAT44S GC/MS/DS system.The detective limits are as low as 20ng/μl. The relative errors aro about10%.
