How to read the energy value of a 2489 or 2487 UV/Vis detector - WKB65958
Article number: 65958
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
- Click the DIAG button when methanol flows through the flow cell.
- Select “2 Sample & ref energy”.
- 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.
Also, there is no official recommended minimum Sample energy ratio compared with Reference. Sample energy is at least 70% of Reference energy in typical systems.
