Technique and Application of CLC-MS

The technique of coupling capillary liquid chromatography (CLC) with ESIMS was introduced in this article. The homemade reverse phase CLC was coupled with ESIMS to analyze the proteolysis of the BSA and TCS. Good separation efficiency is obtained in the peptide mapping and the partial sequence of peptides was deduced in the CID spectrum. Studies show that CLC-MS has high efficiency on sample separation, and has the merits of sensitivity, accuracy and speed on sample identification. CLC has the lower sample consuming and will be more widely used in the proteomics.
