LA-ICP-MS分析校正策略研究

Study of Calibration Strategy for LA-ICP-MS

激光剥蚀电感耦合等离子体质谱分析技术(IA-ICP-MS)以其原位、实时、快速的分析优势,已广泛应用于地质、材料、冶金、考古、医药和生物等领域.除了分析仪器的硬软件研究外,校正分析方略研究一直是LA-ICP-MS元素作图成像分析中的重中之重,尤其是标样的合理制备和使用.就以上各方面做出详细的述评,明确LA-[CP-MS联用分析技术的未来发展方向.

The laser ablation inductively coupled plasma mass spectrometry （LA-ICP-MS） hyphenate technique was applied in geological, material, metallurgical, archaeology, biological, and medicine fields with its prominent advantages such as： in situ, real time and rapidly analysis. It is a modern and powerful analytical tool for the mapping of elemental distribution in samples.And it is urgent that study of calibra- tion strategy for LA-ICP-MS besides developing hard and soft ware of analytical instrument, especially for the preparation and utilization of standard samples.The above various aspects of LA-ICP-MS were reviewed in this paper for the communication with readers. The future trends of LA-ICP-MS hyphenate analytical technique will be understood.
