液/质联用发展至今不到十年时间,业已引起极大兴趣,不仅研制出十余种联结方式,并已出现几种商品接口装置。其原因在于现有仪器的局限性及各领域对有机分析需求的增长。如气/质联用是强有力的分析仪器,但也只能处理整个有机化合物的20%左右(若不衍生化),而液相色谱,由于检测器性能的欠缺(通用性、灵敏度及选择性)和定性困难,使
Less than a decade has passed since the development of the LC / MS, which has drawn great interest not only in the development of more than a dozen linking methods but also in the presence of several commodity interface devices. The reason is the limitations of existing instrumentation and the growing need for organic analytics in all areas. Gas / mass spectrometry is a powerful analytical instrument, but it can handle only about 20% (if not derivatized) of the total organic compound, whereas liquid chromatography, due to the lack of detector performance (versatility, sensitivity and choice Sexual) and qualitative difficulties, so
