How to convert spectrum intensity to AU in MassLynx - WKB9104

Article number: 9104

ENVIRONMENT

  • MassLynx 4.1
  • ACQUITY UPLC PDA

ANSWER

Intensity value divided by 1,000,000 equals absorbance units (AU).

ADDITIONAL INFORMATION

In MassLynx, the Spectrum window of PDA data will show a y axis in AU or Absorbance Units. However, if you copy the spectrum list or change the display to show the spectrum list, you will see intensity values instead.
