Hello,

I am using an Agilent 1100 series Single Quad Mass Spectrometer part # G1956B

Recently while using APCI probe we obtained a peak width error during tuning. The low mass peak region appeared to be have some noise so the system was steam cleaned and the calibration fluid flushed. Now all ions are giving problematic tuning widths.

Also our ESI probe consistently gives the error "ion optics fault 4". Agilent customer service told us this was due to the software but refused to explain how to fix it up and refused to help us update the software.

Is anyone familiar with these problems?

Better yet does anyone know where I can download a manual for this instrument? Agilent only supplied us with some CD's with videos on them which are basically useless for troubleshooting problems like this. I've checked their website and was unable to find any useful information and the service people claim they don't have the manual either, which I find strange and hard to believe.

Thanks for any help anyone can provide.
