LA-ICP-MS INSTRUMENTATION
Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
The Inductively Coupled Plasma Mass Spectrometry (ICP-MS) instrument is a Thermo Electron X7 quadrupole based ICP-MS.
Laser Ablation system
( LA )
The laser ablation system is a commercial New Wave UP213 (New Wave, UK) frequency quintupled Nd:YAG laser.

PRINCIPLES
Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) has been widely used as a powerful micro analytical technique for solid sample analysis in a variety of scientific fields including geological, biological, archaeometrical, environmental, nuclear and metallurgical sciences. Within an ‘ablation cell’ an amount of matter is extracted from the sample by focusing a laser beam on its surface. The energy provided by the laser is absorbed by the sample resulting in vaporization and generation of aerosol which is subsequently transported by a ‘carrier gas’ through tygon tubes to the ICP-MS instrument. Here the sample is firstly ionized by the ICP-torch and then analyzed by the Mass Spectrometry instrumentation.
