The total diethyl ether extractable plasticiser contentis calculated by weight with Gas Chromatography-Mass Spectroscopy (GC-MS)detection to identify and quantify individual phthalates. 定性定量怎么用来计算含量
参6.3.2.7
NOTE It is recommended that suitablequalitative methods be used to identify chlorine containing materials [10]. 感觉不是对氯的含量进行确定，而是对含氯物质进行定性
是定性，是否因为会有干扰呢？
Where appropriate from the stock standard solutions prepare two sets offive phthalate esters GC-MS calibration solutions in n-Hexane to the maximumlinear concentration shown in Table 4
如适当的话，从标准储备液制备2套．．．．制成最大线性浓度．．．
注意prepare……to maximumconcentration是制．．．．成最大线性浓度,
原文的语法可改为：
If appropriate, prepare two sets of five phthalateesters GS-MS calibration solutions in n-Hexane, from the stock standardsolutions, to the maximum linear concentration shown in table 4.
A blank solution shall be run consecutively 空白溶液同法制备，还是连续跑几次？ run可以翻译为制备吗？
