Application Research Database of low frequency LA-ICPMS analysis technology


The data is divided into excel format and JPG image format. JPG image format file and explanation are stored in word document.

The table format data includes: the recommended values of Q and P under low frequency conditions, the results of LA-ICPMS determination of major and trace elements of atho-g under different laser frequencies, and the detection limits of element concentrations of atho-g under different laser frequencies.

The JPG image format data include: the transmission pattern of aerosol inclusions produced by laser ablation of solid samples at 1 Hz and 10 Hz frequencies, the output signal diagram of mass spectrometer, the processing process of LA-ICPMS experimental data, the matching relationship between laser pulse and mass spectrometer data signal, the signal diagram of mass spectrometer data acquisition at 1 Hz laser, the signal diagram of mass spectrometer data acquisition at 1 Hz laser, the signal diagram of mass spectrometer data acquisition at 1 Hz laser The relative error and detection limit of LA-ICPMS experimental data under different laser frequencies were analyzed.

This experiment was carried out in the mineral Micro Analysis Laboratory of ore genesis and Exploration Technology Research Center (oedc), School of resource and environmental engineering, Hefei University of technology from June 1, 2017 to December 1, 2019. The laser ablation system is analyte he of photon machine company. The laser source is compex102f 193nm excimer laser of German coherent company, and the ICPMS is Agilent 7900.

Through the above data, we can get enough length of effective data, which overcomes the shortcomings of high frequency laser experiment. The transmission state of aerosol in the pipeline during laser ablation is analyzed, and a set of superposition integral homogenization processing algorithm is designed.
