Amino acids as contaminants

We offer three different methods for the determination of amino acids as contaminants as described below. In the absence of a specific request, all products will be analysed by GC-MS (A785), the most reliable method.

 

Semi-quantitative determination via GC-FID

(Order code: A445, SOP: A.0.6.)

  • fast screening
  • suitable only for contamination-free amino acids and some amino acid derivatives
  • unsuitable for Histidine and its derivatives
  • not all amino acids will be determined

 

Quantitative determination via GC-FID

by Enantiomerlabeling (A47X, SOP: A.0.6.1.)

  • determination of all proteinogenic amino acids
  • suitable only for contamination-free amino acids and some amino acid derivatives after determination of their enantiomeric purity via GC-FID
  • A minimum of seven working days are required for analysis
  • unsuitable for Histidine and its derivatives

 

Quantitative determination via GC-MS

by Enantiomerlabeling (A785, SOP: A.0.6.3.)

  • precise and fast determination of all proteinogenic amino acids
  • high reliability due to the selectivity of the mass selective detection even for contaminated samples
