Laser Ablation System
Unit 2 exhibits a high sensitivity VG3600 mass spectrometer, attached with an all metal extraction line, and a laser ablation system (Nd-YAG laser) The system consists of one Nd-YAG laser ablation systems, an all-metal extraction line and a VG3600 mass spectrometer. The Nd-YAG system operated in continuous mode, is performed for single-grain fusion and laser step-heating experiments.
