MonoCap C18 HighResolution 2000 is a 2-meter length monolithic silica capillary column which is designed for identifying extremely high number of peptides/proteins for proteome research via LC-MS/MS. MonoCap HILIC-UP is an important addition to the MonoCap C18 HighResolution 2000 column series. MonoCap HILIC-UP can retain highly hydrophilic peptides/proteins which may lead to discovering new peptides/proteins where a C18 phase couldn’t identify. In HILIC, the higher the organic concentration, the greater the retention of more polar analytes. One of the biggest benefits of HILIC mode is, a high organic solvent concentration of the mobile phase will lead to a high sensitivity LC-MS/MS analysis.
