«Atom» software is used in integrated spectral devices for atomic emission and atomic absorption analysis produced by «VMK-Optoélektronika». Development of the new spectral instruments and upgrading of existing devices, birth of new mathematical methods and algorithms for processing spectral information, as well as user stories motivate and promote improvement of the software. This paper presents the main developments and most noticeable changes in «Atom «software for the period 2017 – 2018. The developed 64-bit version of «Atom» software removed the limitation on the amount of recorded sequences of spectra and significantly speeded up their processing by parallelizing the calculations on the processor cores (rather important step, for example, in scintillation atomic emission spectrometry). To implement continuum source electrothermal atomic absorption spectrometry for simultaneous multi-element analysis, we have developed the «Automatic Dispenser» and «Absorption Spectrometer» tools and have implemented the method proposed by D.A. Katskov to linearize calibration dependences in a wide range of concentrations. The possibility of spectrophotometric determination of substances in the solutions of their mixtures has been also implemented. The «Barcode Scanner» and the «Automatic Start of Measurement» tools have been developed to speed up and automate the analysis procedure. The software is supplemented with a set of useful functions designed for further development of analytical methods and programs of analysis.
