LA-ICP-MS Lab TEXT SIZE: A A A

Laser Ablation Inductively Coupled Plasma Mass Spectrometer Lab, locating at the State Key Laboratory of Ore Deposit Geochemistry, consist of a 193nm ArF excimer laser and a Quadrupole-ICP-MS. 

The laser ablation system GeoLasPro (Coherent, USA) uses 193 nm wavelength in solid sampling.  Unmatched energy densities from 1-45 J/cm2, smaller particle sizes from 4-160um, highest signal intensities and lowest elemental fractionation ensure the accurate and shallow depth control, along with flat-bottom craters. 

The Quadrupole-ICP-MS ELAN DRC-e (PerkinElmer, USA) can provide accurate and precise element determination by means of Dynamic Reaction Cell which eliminate polyatomic interferences.  The innovative Axial Field technology makes this instrument stability with relative standard deviation less than 3 % during a non-stop 4 hours measurement.

Nowadays, the Q-ICP-MS is applied to determination Trace Elements and Platinum Group Elements of geological samples, while the combination of LA-ICP-MS focus on Zircon U-Pb geochronology, in-situ element composition of mono mineral and fluid inclusions.
