INDUCTIVELY COUPLED PLASMA MASS SPECTROMETER (ICPMS)


Inductively Coupled Plasma Mass Spectrometer (ICPMS)

INTRODUCTION


Inductively Coupled Plasma Mass Spectrometer (ICPMS) is a very versatile analytical instrument capable of trace and ultra-trace analysis and isotope ratio analysis in aqueous samples. It consists of an inductively coupled plasma ion source, quadrupole mass analyzer, rotary & turbomolecular pump for clean vacuum, easy sample introduction, PC based interface & control & Channel electron multiplier detector. Its sensitivity is 20x106 counts per second per 1 ppm of Indium and detection limits are ppt to ppb for most of the elements.

APPLICATIONS

ICPMS finds numerous applications in Nuclear field, Environmental fields, Geological laboratories, Semi-conductor industries, Chemical/ Pharmaceutical industries, Petro-chemical industries, Forensic laboratories and Research & Development institutes.
