    GB/T 39560的本部分描述了兩種標準方法和兩種參考方法,用于測定在電子電氣產品聚合物中的鄰苯二甲酸二異丁酯(DIBP)、鄰苯二甲酸二正丁酯(DBP)、鄰苯二甲酸丁芐酯(BBP)、鄰苯二甲酸二異辛酯(DEHP)、鄰苯二甲酸二正辛酯(DNOP)、鄰苯二甲酸二異壬酯(DINP)以及鄰苯二甲酸二異癸酯(DIDP)。 本部分的標準方法是氣相色譜-質譜(GC-MS)法與配有熱裂解/熱脫附的氣相色譜-質譜(Py/TD-GC-MS)法。 GC-MS法是定量測定DIBP、DBP、BBP、DEHP、DNOP、DINP 和DIDP 的標準方法,測定范圍從50 mg/kg到2 000 mg/kg。 配有熱裂解/熱脫附的氣相色譜-質譜法(Py/TD-GC-MS),適用于篩選和半定量分析電子電氣產品聚合物材料中的DIBP、DBP、BBP、DEHP、DNOP、DINP和DIDP,測定范圍為100 mg/kg到2 000 mg/kg。 離子附著質譜法(IAMS)適用于DIBP、DBP、BBP、DEHP、DNOP、DINP以及DIDP的篩選和半定量分析,詳見附錄A。由于質譜峰分辨率的限制,用IAMS法測定DBP和 DIBP、DEHP和DNOP的方法尚未確定。 液相色譜-質譜法(LC-MS)僅限于BBP、DEHP、DNOP、DINP 和DIDP的測定,詳見附錄B。由于質譜峰分辨率的限制,用LC-MS技術測定DBP和DIBP的方法尚未確定。 附錄C中提供的流程圖,描述了如何使用兩種標準方法:Py/TD-GC-MS和GC-MS,及如何使用兩種參考方法:直接進樣(DIP)-離子附著質譜(IAMS)和液相色譜-質譜(LC-MS)。 這四種測試方法已經通過測試鄰苯二甲酸酯含量約450 mg/kg至30 000 mg/kg的聚乙烯(PE)和聚氯乙烯(PVC)材料進行評估。 本部分所述的四種方法對其他聚合物類型、鄰苯二甲酸類化合物或上述規定濃度范圍之外的使用未做具體評估。
