Yes lmh. I am using xcalibur. I checked the library and found that.
Thanks a bunch.

The person who did the installation did not emphasize on the library search or its functions because he indicated it is more relevant for the GC-MS or MS-MS. Actually we never did negative ionisation either.

But I guess the equipment training is very basic introductory things.

ISCID is the In Source Collision Induced Dissociation (In Source CID) the source parameter of single stage MS and cone voltage is same, try to increase the cone voltage 30-70 eV and see fragment ions at same RT, same peak start time and peak end time.

Thanks so much for the information Jetamnong.

There are a number of useful things in Xcalibur that they don't tell you about!

(1) If you're using Qualbrowser and want to see the instrument method (it's in the list of views available for a window in Xcalibur), but default all you see is the information about the MS detector. If you press the left and right arrow cursor keys, it will show you all the other instruments: pump, autosampler, other detectors. This is really handy if you are using a process-only copy of Xcalibur to look at data, and haven't got an instrument configured, so the method editor won't open.

(2) The isotope viewer is in different places according to version of Xcalibur. Old versions have it under "Tools" in the Qualbrowser. New versions give it its own tab in the InfoBar (the thing to the left of the spectra and chromatogram windows). It's on the tab with a picture of a formula and an arrow pointing towards a spectrum.

Thanks lmh. That is really useful indeed. This comes in useful if you tried a lot of methods also.
