Center for Meteorite Studies

We perform in-situ isotopic analysis using our Photon Machines Analyte 193 laser ablation system, which ablates the sample into particle sizes on the order of a few nanometers (nm) that can then be directly ionized by the Neptune's argon plasma.

DSCF3110The Analyte 193 consists of an ultrashort pulse length (4 nanoseconds) 193-nm homogenized excimer laser, a 3-inch diameter sample cell, high and low magnification cameras and a built-in beam profiling system. The effective range of spot sizes is from 5 to 150 microns. 
 
Although the presence of matrix elements in the sample does limit analytical precision, the fact that no chemical processing is necessary makes this technique extremely useful in cases where isotopic variations are expected to be significant and high-resolution data coverage is needed.
