MIR 10 Compact Laser Ablation System
Far Infrared Laser Fusing and Heating Systems
The MIR10 is a compact laser systems that provide a versatile method of sampling and analyzing solids for noble gas and isotope-ratio mass spectrometry. The system “floats” above the sample chamber enabling the use of non-flexible tubing to the extraction line for stronger signals and lower blanks. Bake-out ovens can remain under the sample chamber. The MIR10 Laser Fusing & Heating System is a complete, integrated instrument providing full computer control of all laser, beam-delivery, sample-observation and sample-manipulation functions. The 30 watt laser output power is sufficient for micro-feature (in-situ) and bulk analysis (rapid heating diffused – RHD) sampling of difficult materials such as sanidine, feldspar and zircon. The long working distance, joystick control and 1,024 steps of output-power resolution yield optimal results.
Features & Benefits
Gantry mounted system “floats” over stationary sample chamber; ready to use for optimal results
On-axis viewing and lasing at 90° to sample
Long working distance accommodates most sample cell designs
>20W minimum power to the sample, continuously adjustable for power “ramping”
Automated variable spot sizes below 100μm for in-situ analysis and up to 3000μm for rapid heating diffused (RHD) fusions
Software controlled iris “flattens” beam
Software control of all functions, including sample mosaic navigation function
Joystick control for tactile “chasing” of grains in wells
Applications
For ICP, ICP-MS noble gas or stable isotope mass spectrometry. The MIR10-30 excels in:
Laser fluorination (e.g. 18O/16O, 17O/16O, 34S/32S and 33S/32S)
Laser heating (e.g. 13C/12C and 18O/16O)
Rare-gas isotope ratio measurements (e.g. 40Ar/39Ar dating)
Ocean circulation dating using Pb isotopes
Atmospheric chemistry through isotopic analysis of rocks
In-situ dating of geological materials by 40Ar/39Ar
Tracing paleoclimates through isotopic analysis of mammal teeth
