It is equipped with FAB ionization, utilizing&nbsp;a ceasium ion gun and provides mass spectral for delicate thermally labile samples. FAB ionization requires that the sample is mixed with a suitable matrix (typically 3-nitrobenzyl alcohol \u2013 mNBA) and introduced into the ion source on a target probe. At present, full scan and accurate mass FAB analyses comprise the bulk of the work conducted using this instrument.<\/span><\/p>\n\n\n\n<p><span class=\"Normal\">This instrument was installed at the facility and was installed in 2007, at which time it was overhauled and upgraded to utilize the same modern MSS MasSpecII<sup>32<\/sup> Windows based data system that is used by the VG70S instrument.
