Analytical & Isotopically Labeled Standards

Analytical standards & isotopically labeled substances

Thanks to practically identical chemical properties, isotope-labeled substances serve as ideal internal standards to determine the specifications of chemicals. Either by enrichment using 13C or via deuterium labeling, target molecules are equipped with a certain, fixed number of isotopes, which causes a change in physical properties while the chemical properties remain virtually unchanged. Especially for mass spectrometry applications, the use of an internal standard is an essential improvement and quality assurance measures of any given analysis.
