![]() New Wave UP193FX fast excimer laser ablation unit |
|
||
A New Wave UP193FX fast excimer laser ablation sample introduction system was installed in the Department in the 2008. The laser ablation unit produces a laser beam with 193nm wavelength; the short pulse width (<4ns) minimizes fractionation and maximizes irradiance (>3 GW/cm2); while beam homogenization results in an ultra-flat beam profile. The UP193FX utilizes the ATL Ex300Si ArF excimer laser from ATL LaserTechnik while the system is controlled with New Wave Research’s class-leading software and the laser ablation process is monitored using a digital camera. The sample stage is designed to hold thin sections, 25mm cores, and probe-type epoxy mounts. The Department of Geological Sciences’ laser ablation system in housed in the ICP Mass Spectrometry lab and can be readily interfaced with the Agilent 7500ce or IsoProbe. |
