2. Internal standard

The following internal standards (ISs) are used to normalize intensities so that systematic bias, such as run-to-run variation of injection volume and sensitivity of mass spectrometry, is canceled. The IS1 is used to for this purpose. IS1 and the IS2 are used for normalizing migration times in electropherograms.

  • Cation
    • IS1 : Methionine sulfone
    • IS2 : 3-Aminopyrrolidine
  • Anion
    • IS1 : D-camphor-10-sulfonate
    • IS2 : Trimesate
