(EN) LEA-S500 – is a modern powerful atomic – emission spectral instrument with multichannel spectrum registration, combining in itself innovation technologies in the area of laser, spectral, measuring, digital equipment and software and permitting elemental (chemical) analysis of a sample in minutes. The detectable elements are from H to U, measuring range is to 100%. Necessary weight of the analyzed material is from 50 nanograms. The time period of multi-element analysis including sample preparation is 1 – 15 minutes. 400 analyses on determination of material homogeneity take about 7 minutes.
