Wavelength Calibration test aborted by system - HPLC 1100 DAD detector

Hi

Are you getting any error code in logfile or on controller.

No, no error codes in the results file or the log book, the alpha and beta deviation are very high though

There could be hardware issue like motherboard but before that do lamp intensity test then try wave length calibration again.

The lamp intensity test fails - does not get aborted but fully fails. Any information on how I can tell if it's a motherboard issue? Thanks 

This lamp you bought from agilent..

It's original???

Before replacing lamp, what problem / error you were facing..

Before replacing lamp, what problem / error you were facing..

Yeah it was a brand new lamp from agilent. The problem I was having was very bizarre detector results, when just running the mobile phase the detector signal was just completely flat, with no noise at all which is unusual and then with blank injections I was getting large square spikes in the baseline, or negative peaks, the below are from two consecutive injections of 90% acetones

The system had run without issue the day previously, although it was shut down for a month before that  

When there was issue with peak and baseline that time detector lamp was litting.

That time, you should put new mobile phase and new column or any other column to see peak n baseline.

I assume that there is no leak..

After changing lamps, did you reset the lamp hour time.

Yeah I reset the lamp hour time and there does not appear to be any leaks anywhere. I did make new mobile phases when the problem first occurred (and everyday that I have attempted to troubleshoot the instrument) but it didn't change anything. I did not swap out the column because it had worked fine the day before and did not think that column issues would present like that

Okay.

Use your old lamps with new or any other good column and run to see any problem.

Just notice, there any error appear or not..

Is the model of your DAD a G1365A or G1365B? If so, you can try the intensity test without the flow cell. If you need the flow cell, make sure you have fresh new Water in the flow cell (flush system with water).

From what I can read so far, I would probably remove the column and put a union instead and see if you run a blank if you get those peaks again. To rule out Column.
