How to read the energy value of a 2489 or 2487 UV/Vis detector - WKB65958

OBJECTIVE or GOAL

Read the energy value of a 2489 or 2487 UV/Vis detector.

ENVIRONMENT

• 2487 Dual-Wavelength Absorbance Detector
• 2489 UV/Vis Detector

PROCEDURE

1. Click the DIAG button when methanol flows through the flow cell.

2. Select “2 Sample & ref energy”.

3. Note the Sample and Ref energies.

ADDITIONAL INFORMATION

There are no official recommended minimum energy levels. The requirement is to be able to pass start-up diagnostics when powered on and pass the wavelength verification as noted in the PM protocol.

Sample energy should be at least 70% of Reference energy.
