“…A Grand spectrometer 24 equipped with a concave diffraction grating (2400 lines/mm) and two multichip photodiode arrays, which were a key component of a multichannel analyzer of emission spectra (MAES), allowed spectrum registration in two spectral ranges: 185 -350 and 385 -470 nm. The MAES system is supplied with ATOM software package, which allows spectral data processing: measurement of analytical signals with background correction, construction of calibration curves and calculation of element concentrations.…”

The possibility of direct analysis of soils by two-jet plasma atomic emission spectrometry was investigated using certified reference materials of black earth, grey desert and red soils. It was shown that As, B, Cd, Cu, Hg, P, and V could be determined after a 2-fold, and Be, Co, Cr, Ga, Nb, Pb, and Zn-after a 10-fold dilution of the samples by a spectroscopic buffer using calibration samples based on graphite powder. The strongest matrix effects were revealed for red soil having the highest Al and Fe concentration, which led to the overstated concentrations of some elements. The overstating factor depended on analyte concentration and was no more than 2. A clear advantage of the suggested technique over existing methods is the simple sample preparation process, which requires no reagents except a spectroscopic buffer, and possibility of using the same calibration samples for analysis of different soils.

The main directions in the development of the spectral systems for scintillation atomic emission analysis of powdered geological samples are aimed at increase in the sensitivity, spectral resolution, and speed of the spectrum analyzers to reduce the detection limits. The goal of the study is developing of high-speed MAÉS analyzers with hybrid assemblies of the arrays of 14 multichannel photodetectors of two types: high-sensitivity BLPP-2000 and BLPP-4000 photodetector array with high spatial resolution and theoretical estimation of the signal-to-noise ratio when recording scintillation and integral spectra with aforementioned photodetectors. The high-speed MAÉS analyzers with BLPP-2000 and BLPP-4000 photodetector arrays are designed so as to provide parallel readout of photodetectors in hybrid assemblies. They consist of 14 BLPP 2000 or BLPP 4000 photodetectors and records the spectra in the 190 – 350 nm wavelength range on a «Grand» spectrometer. The minimum exposure time is 0.9 and 1.7 msec, respectively. It is shown that in measurements of spectral-line intensities using BLPP-2000, the signal-to-noise ratio is 3 times higher in integral analysis and 5 times higher in scintillation analysis compared to measurements with BLPP-4000 photodetector array.
