GC—MS法测定液态松香助焊剂中邻苯二甲酸酯类物质

Determination of phthalate in liquid flux rosin base by GC-MS

本文研究的GC-MS法测定液态松香助焊剂中邻苯二甲酸酯类物质,具有灵敏度高、准确、简便等特点。方法的检出限DBP、DEHP、DNOP均小于0.1mg/L,BBP小于0.3mg/L,回收率均大于85%,相对标准偏差均小于5%。

The determination of Phthalate in Liquid Flux Rosin base by GC-MS was high sensitivity, accuracy, simple.The detection limit was DBP, DEHP, DNOP 0.1 mg/L,BBP 0.3mg/L.The recoveris were over 85%.The rela- tive standard deviations（RSDs） of contents of formaldehyde was below 5%.
