 In this step molecules bind the adsorbent and interferences pass through. 
 Next, the column is washed with the mobile phase to eliminate the contaminants while ensuring the analyte remains bound. 
 Finally, peptides are eluted in an appropriate buffer solution with polarity or charge that competes with interaction with the solid phase.
