DEVICE AND METHOD FOR ONLINE DETECTION OF ELEMENTS IN LIQUID SAMPLE

WIPO Patent Application WO/2022/062118

A1

A device and method for online detection of elements in a liquid sample, which belong to the field of optical analysis instruments; a specially designed ultrasonic atomization auxiliary sampling device is used to realize continuous and rapid sample introduction, embodying the features of real-time and online analysis of the present device, and the presence of a standard sample enables the detection to have higher accuracy; and a laser pulse is used to breakdown a sample, and a spectral analysis apparatus and a time-resolved image sensor are used to analyze an ablation process and plasma characteristics, so as to achieve online and real-time test of the sample. The detection system can be used in the field of on-site rapid detection of heavy metal elements and other important metal elements in marine and fresh water environments, can be applied in the fields such as real-time online detection of metal elements in industrial wastewater discharge, and can also be used in basic research in the field of scientific research.
