ICP-MS (Inductively Coupled Plasma Mass Spectrometer)


Details of analysis, type of analysis etc

Trace and REE analysis (solution mode) of rock, sediments and water/liquid samples.


The plasma generated in the ICP torch creates a very hot zone that serves a variety of functions. During their voyage into the plasma, the liquid droplets containing the sample matrix and the elements are dried to a solid, and then heated to a gas. As the atoms travel through the plasma, they absorb more energy from the plasma and eventually release one electron to form a singly charged ion. These ions exit the plasma and enter the quadrupole through interface region, where they are separated and counted using an electron multiplier.


The technique is very useful for elemental analysis of rocks, ores, minerals, water samples, environmental samples and biological samples in parts per billion levels. Rare earth elements can be determined from sample solution directly without carrying any separation and pre-concentration, with ICPMS.

Guideline for samples
  • Applicant must send their solid samples in powder form (-200 mesh size) of 5 gm to 10 gm.
  • Sample name, type of rock / matrix (e.g. granite, basalt, carbonate, clay etc.) must be mentioned clearly while sending their samples.
  • Water/Liquid samples must be filtered properly (no turbidity) and sent with proper seal.
  • Samples can be sent to the OIC of lab (Please mention application reference number):
