What are the units for area and height for an absorbance detector in MassLynx? - WKB2016

ENVIRONMENT

• MassLynx 4.1
• MassLynx 4.0
• Absorbance detector: for example, PDA, UV, TUV, ACQUITY UPLC PDA Detector, ACQUITY UPLC PDA eλ Detector, ACQUITY UPLC Tunable UV Detector, Waters ACQUITY 2996, 2998 Photodiode Array (PDA) Detector, 996 Detector, 2489 UV/Visible (UV/Vis) Detector
• Chromatogram window in MassLynx

ANSWER

MassLynx 4.0 SP3 and higher:

Height is reported as µAU.
Area is calculated as µAU*minutes (not seconds).

Note: For all absorbance detectors in MassLynx, the y axis is labeled AU not µAU.
