主题：【求助】求助家具中富马酸二甲酯的检测方法

富马酸二甲酯具有升华特性，因此用GC比用HPLC要好。
可用萘作为内标物，最好用氘代物。DB-WAX柱子非常合适，不过DB-5MS也勉强可以，稍稍脱尾。

很多客户要求做到小于0.1ppm

1月29日，欧盟成员国通过了“保证含有富马酸二甲酯的消费品不会投放欧洲市场”的决议草案。目前，该决议仍处于欧洲议会审查阶段，预计将在5月1日前正式生效。
草案明确规定，如果消费品或其部件中富马酸二甲酯的含量超过了0.1毫克/千克，或者产品本身已声明了其富马酸二甲酯的含量，就将被认定为“含有富马酸二甲酯”的产品，其将禁止进入欧盟市场流通和销售。

皮革纺织品中富马酸二甲酯的检测方法

Abstract;A solid phase extraction-GC/MS method was applied to determination of N,N-dimethylformamide(DMF) in water and sediment. Five hundred milliliters of water samples, spiked with DMF-d7, are passed through a C18 cartridge and two active carbon cartridges in series. DMF absorbed on the active carbon cartridges is eluted with 3ml of methanol. The eluate is concentrated to 0.5ml and then added 4.5ml of ethyl acetate. After dehydration with anhydrous sodium sulfate, the eluent is concentrated to 1ml and determined by GC/MS. Sediment samples are spiked with DMF-d7 and extracted three times by 20ml portions of purified water. The subsequent procedure is the same as water samples. The overall recoveries were 88.5% to 112% from water samples and 94.5% from sediment samples. The detection limits were 0.065.MU.g/l in water samples and 1.9.MU.g/kg in sediment samples.

如果一旦检出就是不合格，那仪器的检出限就至关重要了。
哪位知道DMF的检出限是多少？

和分析方法也有关系。方法检出限比仪器更重要。实际上经常仪器可以而方法不行。

非常感谢无私提供资料的朋友们

大家比较通用的是0.1ppm

用gc/ms来测,柱子hp-5ms
