List: We have a PQExcell and just meticulously installed the first replacement detector. Visually all seems correct and we have a good vacuum but, we are getting no indication of a signal at all. We are not just getting background or even zeroes but a blank under our ICPS column in our tuning panel and in other locations where we can monitor a signal. We are reasonably confident that the detector has been installed correctly but we are obviously experiencing a serious problem. Any suggestions especially from other PQExcell labs would be appreciated.
Thanks in advance
