Wikimedia Commons has media related to High performance liquid chromatography. Take care of your HPLC, it's the right thing to do! Chromatography can be described as a mass transfer process involving adsorption. A volatile organic acid such as acetic acidor most commonly formic acidis often added to the mobile phase if mass spectrometry is used to analyze the column effluent. An increase in counter ion with respect to the functional groups in resins concentration reduces the retention time. Bibcode : JChEd.

Taking the illustration above one can see that all of the peptides are out by 40 minutes.
The smaller particles generally give higher separation efficiencies. Its composition and temperature play a major role in the separation process by influencing the interactions taking place between sample components and adsorbent. HPLC has been used for manufacturing e. HILIC most often uses a bonded polar stationary phase and a mobile phase made primarily of acetonitrile with water as the strong component.
However, convenience comes at the cost of specificity and coverage of a wide range of drugs.
