如何测定水中MTBE(甲基叔丁基醚)?

气相色谱(GC)

  • 请教各位高手,关于水中mtbe的浓度如何测定,有那位涉及过,望指点一下。详细条件是什么,各个温度、进样是水样还是有机溶剂样等?

    Determination of methyl tert-butyl ether (MTBE) in Chinese fuels by gas chromatography/mass spectrometry and gas chromatography/flame ionization detector.

    A method was developed to determine the concentration of methyl tert-butyl ether(MTBE) in gasoline, diesel and heating oil by gas chromatography(GC) with mass spectrometry(GC-MS) or flame ionization detection (FID). The diluted gasoline was directly injected into the GC, and the complete separation of MTBE from co-eluting hydrocarbons was not required. GC/MS or GC/FID method can be used to analyze MTBE in different concentration range and have good consistency.
