Se in soil by LIBS calibration
Description
This data is intended for LIBS determination of selenium in soil on the following types of samples: loose soil powder, soil fixed on adhesive tape and soil tablets. The LIBS spectra of soil samples with selenium content <0.5 and 5, 15, 40, 115, 230, 460 mg/kg are presented here. File names content the following designations: 0.00%Se means that sample content <0.5 mg/kg of Se; 0.001%, 0.003%, 0.008%, 0.025%, 0.050%, 0.100% mean that sample content 5, 15, 40, 115, 230, 460 mg/kg of Se respectively.

Steps to reproduce
To get a contaminated soil sample with 23000 mg/kg selenium, we add 100 ml of distilled water Na2SeO3 powder (98%) solution (50 g/l) to 99.3 g of soil milled into powder. Next by mixing the contaminated sample with the original soil we prepared samples with selenium content of 5-460 mg/kg.
