What are aberrationsdnd

Mass spectrometry is defined as a technique that involves analyzing ions according to their mass to charge ratio (M/Z). This technique can be used to determine the mass, structure, and relative abundance of ionized compounds.

The JEOL mass spectrometer is a High-Performance Gas Chromatograph Time-of-Flight Mass Spectrometer. It is interfaced with an Agilent 7890A Gas Chromatograph with auto sampler. It is equipped with an EI only source and an EI/FI combination source that is capable of field desorption. GCMS in EI mode a NIST library can be used to help identify chromatography peaks. Samples can be introduced into the mass spectrometer by GC or by an insertion probe. Field ionization/field desorption is a soft ionization technique is ideal for determination of molecular mass of neutral molecules. FI/FD shows little or no fragmentation of the molecule especially with thermally liable neutral compounds. The FI mode can be used with the GC to determine the molecular ion of volatile samples that fragment easily in EI mode. The high resolution and high mass accuracy makes it possible measure exact mass and to determine elemental composition of a compound.
