Recently our lab bought a refurbished agilent 1100 series HPLC. I assume the instrument had been inactive for some period of time. So today I went to purge the pump with 100% methanol. However, out of the 4 channels only C and D channel was able to purge solutions. Both A and B didnt seem to be able to even draw solutions from their respectively reservoir.
I was wondering if anyone would have idea what the problem is or would I need to use a syringe and draw the air out of the degasser for starters.
Thank you very much
