Mass Spectral Fragments Lost

COMMON MASS SPECTRAL FRAGMENTS LOST Thomas J. Bruno and Paris D. N. Svoronos... 

Mass spectral fragmentation of the 1-phenyltetrazolines (327) involved loss of the PhNCX moiety.616 Thus for X = O and S the fragments PhN=C=0 and PhN=C=S were lost while for X = NHR1... 

Useful interface which Is applicable to a wide range of molecules. The volatile solvent molecules are stripped from the sample and lost in a process similar to that used in the early jet separators used in GC-MS. The heavier sample molecules enter the MS and can be ionised by the standard methods of El, PICI or NICI. Gives spectra with El fragmentation which can be referred for identification to El spectral libraries built up over many years. No solvent background thus sensitive to the 1(h g level. Solvent flow rate up to 1 ml/min, mass range up to 1000 amu...
