Photon Machines Analyte G2

Installed in summer 2011 this instrument is designed for laser ablation ICP-MS analyses of a range of solid materials. Based on an ATLEX fast excimer laser system, the unit also has full (0-100%) energy attenuation, beam homogenization optics and an ANU-style two volume cell for high sensitivity and rapid response times. Laser spot sizes vary between ~5-250 ┬Ám and include circular, square and slit-shaped spots. We also have an adjustable aperture that allows for customizable slit and square-shaped spots. Sample holder options include 9 × 25 mm rounds or 3 × 25 mm rounds plus 4 × 50×25 mm thin sections. We have have a cryocell for ablation of ice and other temperature sensitive matrices.

The G2 is coupled with either the Therm XseriesII Quadrupole for trace element analyses and U-Pb dating of zircon, or with the NuPlasma MC-ICP-MS for in-situ analysis of Pb or Sr isotopes.
