193 nm laser ablation systems
Excimer lasers with 193 nm wavelength and HelEx dual-volume laser ablation cells
About
Excimer lasers with 193 nm wavelengths can be used to ablate many solid materials at spot sizes of 20 to 400 microns and samples can be drilled or rastered. The laser ablation chamber available is the first of its kind developed and still provides some of the best ablation characteristics. It is coupled to a Coherent ExciStar ArF 193 nm nanosecon-pulse laser system that has a large dynamic range of possible laser energies. The system can be selectively coupled with the above machinery. Detection limits are generally in the high ppb to ppm (parts per billion to parts per million) range. Example materials analysed are: minerals, glass, fossils, pottery, bone, teeth, and paint.
Two 193 nm laser systems are available, each can be coupled to an Agilent 7900 Q-ICP-MS, Agilent 8900 QqQ-ICP-MS, and/or nu instruments Plasma III MC-ICP-MS.
