my 1200 VWD lamp comes on but the detector module remains not ready, what is going on?

My 1200 VWD lamp turns on fine, however, the detector module remains not ready, why?

  • Hi ncrystalj, what might help with guiding you through this issue is posting the revision and type of software you're using. Most software has this information under Help > About. Please post the full software name and its revision. Without knowing that information, we can't provide specific instructions, but I will say generally that the reason for which any module is not ready should be able to be found out by hovering over the Not Ready status box in the software (usually a yellow rectangle). It might not be the lamp that's causing the detector to be Not Ready; what does that message say?

  • I do now see that it's lost its calibration.

     

    In regard to the version info here they are:

    OpenLAB CDS ChemStation Edition - Rev. C.01.07 SR3 [465]

    Agilent OpenLAB CDS ChemStation LC and CE Drivers

    product version - 2.17.29

    driver version - A.02.17 [32]

     

    Thank you valentinrusu

  • What likely happened is the wavelength check that is done after lamp ignition failed. When the lamp is switched on, the detector waits 1 minute to warm-up the lamp. Then a check of the deuterium emission line via the reference diode is performed. If the emission line is more than 3 nm away from 656 nm, an error message is generated. Do you see any other errors? Is the lamp newly installed? It's possible the lamp might need to be replaced if, for example, the intensity test fails but the cell test passes. Otherwise, you can perform the wavelength calibration described in your User Manual, under the Tests & Calibrations section of the Maintenance chapter.
