There could be issues with either control signals to the HED power supply or the power supplied to the HED power supply. These electronic issues are down in the depths of the instrument and should be handled by a trained service engineer. Please contact…
A bit late maybe, but you can set the printer within the macro using the MYPRINTER = "name of printer". Use the command before your STARTPRINT command, and then at the end of the macro remove it (REMOVE MYPRINTER), so that it will only be active for the…

You should always consider that after re-igniting the lamp, it typically requires 60-90 minutes establishing a stable detector signal.
Based on this it does not always make sense and saves lifetime shutting off the lamp.
Keep constant flow 1.2 ml/min into the MS and do a Pulsed Splitless injection, tips in the help section of the Operating manual. Your system's diffusion high vacuum pump can only handle 2.0 ml/min maximum so do not exceed that ever.
If you have a 30m…
In Manual Tune, PFTBA closed, set the scan range to 10-100, then click on the spectrum scan button. The spectrum will show repeatedly in the middle window to the left at the long red arrow..
Beautiful. Does the spacing change with a different column flow rate? If this is 1.2 ml/min, for example, is it different with only 1.0 ml/min? If it changes and you did the inlet and column maintenance properly, the issue is before those. If it does…
How do you split the sample? Is it two different injection ports? Two different columns into the injection port? Or a two way splitter - purged or unpurged?
Are you injecting split or splitless? Please upload the acqmeth.txt file that is in Windows…
Hello,
Error 1213 typically comes with other errors that truly describe the issue, like the 2150 error you are getting.
First, check the cone orifices. Use a microscope or powerful magnifying glass. If they are clogged or salted over, clean. The opening…
