With the advent of low dispersion, fast aerosol transport technologies used in laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), the need for high-repetition rate lasers has become crucial. This work reports on the analytical performance of a LA unit with an experimental 500 Hz laser head, interfaced with a quadrupole ICP-MS instrument, and comprising a commercial two-volume ablation chamber (HelEx II) and low-dispersion aerosol transport device (ARIS). The system was tested for potential problems related to particle saturation, elemental fractionation, ionisation efficiency, etc., prior to validation as a high-resolution LA-ICP-QMS imaging tool with a high mapping rate.

高重复频率激光头（500 Hz）用于HR LA-ICP-QMS成像的分析性能

随着激光消融电感耦合等离子体质谱法（LA-ICP-MS）中使用的低色散，快速气溶胶传输技术的出现，对高重复频率激光器的需求变得至关重要。这项工作报告了具有实验性500 Hz激光头，与四极杆ICP-MS仪器连接，包括商用两体积消融室（HelEx II）和低分散气溶胶传输装置（ARIS）的LA装置的分析性能。）。在验证该系统是否具有高映射率的高分辨率LA-ICP-QMS成像工具之前，对该系统进行了与颗粒饱和度，元素分离，电离效率等相关的潜在问题的测试。
