文摘The detector,as well as being an essential supporting device for the gas chromatography(GC) has also played a critical role in the development of the technique as a whole.The mass spectrometer(MS) is still the commonly praised detector as before.In fact,the information of fragmentation patterns is seldom used in practice,and the GC-MS instrument is even more expensive.For today's analytical problems,it seems that element specific detectors can and should be used for many applications rather than GC-MS.
