GB/T 39560的本部分描述了两种标准方法和两种参考方法,用于测定在电子电气产品聚合物中的邻苯二甲酸二异丁酯(DIBP)、邻苯二甲酸二正丁酯(DBP)、邻苯二甲酸丁苄酯(BBP)、邻苯二甲酸二异辛酯(DEHP)、邻苯二甲酸二正辛酯(DNOP)、邻苯二甲酸二异壬酯(DINP)以及邻苯二甲酸二异癸酯(DIDP)。 本部分的标准方法是气相色谱-质谱(GC-MS)法与配有热裂解/热脱附的气相色谱-质谱(Py/TD-GC-MS)法。 GC-MS法是定量测定DIBP、DBP、BBP、DEHP、DNOP、DINP 和DIDP 的标准方法,测定范围从50 mg/kg到2 000 mg/kg。 配有热裂解/热脱附的气相色谱-质谱法(Py/TD-GC-MS),适用于筛选和半定量分析电子电气产品聚合物材料中的DIBP、DBP、BBP、DEHP、DNOP、DINP和DIDP,测定范围为100 mg/kg到2 000 mg/kg。 离子附着质谱法(IAMS)适用于DIBP、DBP、BBP、DEHP、DNOP、DINP以及DIDP的筛选和半定量分析,详见附录A。由于质谱峰分辨率的限制,用IAMS法测定DBP和 DIBP、DEHP和DNOP的方法尚未确定。 液相色谱-质谱法(LC-MS)仅限于BBP、DEHP、DNOP、DINP 和DIDP的测定,详见附录B。由于质谱峰分辨率的限制,用LC-MS技术测定DBP和DIBP的方法尚未确定。 附录C中提供的流程图,描述了如何使用两种标准方法:Py/TD-GC-MS和GC-MS,及如何使用两种参考方法:直接进样(DIP)-离子附着质谱(IAMS)和液相色谱-质谱(LC-MS)。 这四种测试方法已经通过测试邻苯二甲酸酯含量约450 mg/kg至30 000 mg/kg的聚乙烯(PE)和聚氯乙烯(PVC)材料进行评估。 本部分所述的四种方法对其他聚合物类型、邻苯二甲酸类化合物或上述规定浓度范围之外的使用未做具体评估。
