It's happening again...

I had to talk with my supervisor this morning.
In my in-box, there are 6 sets of samples to be analyzed, the oldest dating 01-22-07. My two new instruments were received the first week of January, and one of them was installed on January 8th; the second instrument's installation was delayed due to a software malfunction, which was corrected by the service/maintenance technician last week (Jan 29th). After nearly a month of instrument assembly, method development, trial injections of standards, and then the running of my method detection limit study, neither instrument is yet operational. The second instrument (we'll call it DB1701) is still in its initial stages of assembly/development/trial injections for ECD analysis. The NPD analysis from that instrument appears to be okay, but then again, it also did on instrument #1 (aka DB5). However, when running and then processing the method detection limit study on DB5, I'm lacking consistent sensitivity and thus consistent, reproducible, reliable results. The ECD analysis from DB5 seems to be working fine, so that's all I'm left with that's working: one available testing method out of 4 that I need.
When I say that it's happening again, I mean the back-log. There are 78 samples that need to be reported, and I don't have a functioning instrument.
When I talked to my supervisor this morning, I told him my concerns, and that I am really afraid that I'm going to end up in the same situation I was in last summer. I said that I took responsibility for those delayed reports, because they were my samples and I felt like I should have been able to get my instruments working, but I can't do it again. He said that we can't report any results using a method that has not passed the EPA MDL-study; I told him that I know this is the case and that is precisely why I'm concerned. It's only a few days short of a month that I've had the instrument(s), and I'm already 78 reports behind. I don't want to dread coming to work every day like I did towards the end of last year. I don't want to end up in the same helpless and hopeless situation. And I am not taking responsibility for the late reports if and when that is the case.
I don't make enough money to keep me here if I'm hating my job.
