Quick Mass Determination

Compact Mass Spectrometer (ESI, APCI/TLC/MS), Advion, USA.

Mass spectrometry’s characteristics have raised it to an outstanding position among analytical methods: unequalled sensitivity, detection limits, speed and diversity of its applications. Most applications are oriented to proteomic, metabolomic studies, drug discovery and metabolism. In addition to other applications such as pollution control, food analysis and forensic medicine.
