OBJECTIVE or GOAL
Read the energy value of a 2489 or 2487 detector.
- 2487 Dual-Wavelength Absorbance Detector
- 2489 UV/Vis Detector
- Click the DIAG button when methanol flows through the flow cell.
- Select “2 Sample & ref energy”.
- Note the Sample and Ref energies.
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.
