A robotic arm-based combined system for LIBS field analysis and laser ablation sampling

Abstract

This invention discloses a combined system for LIBS field analysis and laser ablation sampling based on a robotic arm, comprising a control platform, a robotic arm, and an integrated operation module. The control platform includes a laser source, a robotic arm controller, a LIBS spectrometer, a gas path processing module, a gas supply module, and a central control processing unit. The integrated operation module includes an optical path system, a galvanometer system, and a detection module. The detection module includes a housing, a flexible enclosure, a focusing lens, a focusing system, a laser displacement sensor, a ring illumination lamp, a vision system, a LIBS light signal collector, an air inlet, and a sample collection module. This invention enables automated analysis in various scenarios, including fieldwork, factory operations, and laboratory mass spectrometer docking. It can adapt to samples of various complex shapes and sizes, as well as irregular sample surfaces. Through combined analysis, it improves analysis speed and specificity, reduces sample consumption, and ensures analytical quality.
