Amino Acid Analysis
Required in many disciplines and applications Components of proteins Metabolic intermediates Bound vs. Free Nutritional value of foods and feeds
Difficult analytical problem Separation
o Wide range of propertieso Slight differences between pairs
Detectiono No chromophoreo Wide concentration range

Separation of Amino Acids
Cation-exchange Original method for amino acid analysis
Large historical data base of uncommon amino acids
Realistic run times near 30-60min
Reversed-phase HPLC of derivatized amino acids Best separation selectivity
Best sensitivity
Shortest run times
2012 Waters Corporation 4
Detection of Separated Amino Acids
Post-column Reaction Ninhydrin or OPA with ion-exchange most common
ESI-MS with reversed phase HPLC and no derivatization
Pulsed Amperometric Detection
Pre-column derivatization Many reagents used successfully; some commercialized
Add UV or fluorescence detectability
Improve chromatography
Usually faster and more sensitive
Successful use requires care
