Well, looks like the GC-MS needs a lot of attention recently. After a fatal crash (or rather more than one), the connection between the computer and the instrument was down for good. Well after uninstalling the software and some additional cleaning up by hand, we have reinstalled and reconfigured the software.
All problems solved – and the beast is running nicely again. No data were lost either – so the operation was a success. A couple of hours well spent. Tomorrow is my day on the instrument and I am looking forward to some improved results (*keepingmyfingerscrossed* despite being a scientist).
