Determination of Optical Purity of Amino Acids and their Derivatives
   
Introduction 
Amino acid derivatives are the starting materials for peptide synthesis. Enantiomeric pure substances are required for the synthesis of optically pure peptides.
 
We offer three different methods for determination of optical purity of the amino acids of peptides  
FID-method 
for amino acids and amino acid derivatives and, if high standard deviation is acceptable, peptides
   A430 Free amino acids
   A440: Amino acid derivates
   A410: Peptides 		 
GC-MS method (A790)
for highest reliability 		  
HPLC on chiral phases (A530)
for chiral components which can not be separated by GC		  
Our service:
You send your sample to us by post. Cleavage or hydrolysis (if necessary) is performed in our laboratory to ensure standardized conditions. In one to three days after receipt of your sample you receive the results of the analysis
