Pierce™ Graphite spin columns improve phosphopeptide analysis by efficiently binding hydrophilic peptides and efficiently removing urea, salts and other contaminants before mass spectrometry analysis.

• Convenient spin format for parallel processing of multiple samples
• High-binding capacity with recovery of up to 100 µg of hydrophilic peptides per column
• Porous graphite resin for cleaning up phosphopeptide samples before MS analysis

Enable fast and efficient capture, concentration, desalting and elution of hydrophilic peptides in less than ten minutes.
