LIBS spectra of the LIBS calibration standards with five different Se (VI) concentrations (10, 20, 50, 150, and 200 mg/kg) in the wavelength regions where the a Se (I) and b C (I) emission lines were observed. In (a), the two peaks denoted by “*” are the Se (I) emission lines at 203.99 and 206.28 nm. The C (I) lines at 247.86 nm, shown in (b), originated from the membrane filter material
