Chemical structures of isotope-labeled amino acids including Alanine, Glutamine, Leucine, Phenylalanine, Tyrosinamide, and Tyrosine used as internal standards in mass spectrometry.

How Amino Acid Internal Standards Improve Data Reliability in Mass Spectrometry

Mass spectrometry (MS) has become one of the most powerful tools in biological and chemical research, offering unmatched sensitivity and precision in detecting small molecules. From clinical diagnostics to metabolomics, researchers rely on mass spectrometry to extract accurate data that drives critical decisions. But as with any analytical technique, precision depends heavily on standardization. This…
