摘要: Capillary electrochromatography (CEC), along with other miniaturised chromatography techniques, such as capillary LC, offers the most benefit when efficiently coupled to mass spectrometric (MS) detectors. In conventional one-piece CEC columns, dispersion in open connecting tube between packed column and MS source reduces chromatographic performance unacceptable levels. This paper examines effect on of various column-tube arrangements suggestions practical way CEC-UV-MS. Comparisons theoretical measured values for these different are shown.
