These columns are ready-to-use centrifuge columns of porous C18 reverse-phase resin with excellent binding and recovery characteristics for peptide sample preparation for mass spectrometry and other methods.

• Each column contains 8 mg of C18 resin
• Removes interfering contaminants by reducing signal suppression and improves signal-to-noise ratios and sequence coverage
• Processing yields high-quality spectra and is effective for a variety of reverse-phase-compatible contaminates
• Works with a wide variety of load volumes and concentrations with no need to reduce sample volume before application
• Easy to handle and requires no special equipment to process multiple samples simultaneously
• Special resin allows excellent recovery percentages, even at low sample loads

The spin column format allows processing of multiple samples from 10 to 150 µl in approximately 30 minutes without laborious repeat pipetting or the use of any special equipment. The C18 reverse-phase resin provides excellent binding and recovery characteristics for a wide range of peptide concentrations and load volumes.
