On-Line Desalting Cartridges
The MassPREP On-Line Desalting Cartridges can effectively desalt
proteins prior to LC/MS analyses with minimal sample handling. Salts can compromise the quality of protein analysis by interfering with ionization and/or forming adducts with the investigated proteins. The reversed-phase, phenyl material contained in MassPREP On-Line devices successfully “traps” proteins, allowing the salts to be washed away prior to protein elution into the mass spectrometer. In addition, combined with an appropriate HPLC system injector and injector wash solution, the cartridges can be used for the sequential analyses of different samples.
