SPECTROMETER
Atomic Emission Spectrometer with Microwave Plasma «Spectro-Sky»
LLC «LIT» of GC «Skygrad» together with JSC «Spetsmagnet» developed a new atomic emission spectrometer with microwave plasma (AES-MP) «Spectro-Sky» of two modifications: «M» and «REE».
AES-MP "Spectro-Sky" is a multi-channel automated atomic emission spectrometer with a source of excitation of the spectra of the studied samples in an electrode capacitive microwave plasma (СMP) discharge and is intended for analysis of the chemical composition of complex technological solutions, metals and alloys previously converted to solution.

Advantages of AES-MP «Spectro-Sky»:
· Simultaneous determination of the content of over 70 chemical elements in various matrices;
· High accuracy and speed of analysis;
· Low cost of analysis;
· Minimum values of interelemental influences and matrix effect;
· High stability and reproducibility of results;
· A wide range of linear dependence of the signal on the content of the determined elements (4-5 orders of magnitude);
· The use of nitrogen or air to form an CMP discharge instead of the mandatory use of expensive high-purity argon in an IСP spectrometer;
· It is easy to solve the problems of analysis of complex materials without separation of the base, including for rare-earth elements (REE) in their concentrates;
· The purchase of expensive sources of resonant radiation (lamps with a hollow cathode) is not required and there is no need to use explosive and toxic gases.

Microwave source technical specifications
Protection against parasitic microwave radiation is provided by the use of transcendental transitions on the plasma torch and the protective casing of the magnetron block.
AES-MP «Spectro-Sky» software
AES-MP «Spectro-Sky» is controlled by a personal computer using the specialized software "Graduation, version 5.1". The software is compatible with Windows98 / 2000 / XP / 7/8/10, has the following features:
• provides full control of all functions of the spectrometer registration system;
• provides storage and graphical representation of spectra in a database with convenient navigation, scaling, identification of spectral lines, etc.;
• contains a database of spectral lines of a microwave plasma source for their identification in the spectrum, a qualitative analysis and the production of close spectral lines for estimating overlays;
• provides automatic correction of the drift of spectral lines by wavelengths on all 12 CCD arrays during each measurement of the spectrum or analysis and in the procedure for special measurement of shear according to the assigned sample;
• allows individual accounting of the magnitude of the spectral background for each analytical line on both sides of it at multiple arbitrary designated spectral locations, which allows determining the analytical signal without taking into account spurious radiation of the plasma, thereby increasing the sensitivity and accuracy of measurements;
• provides for the use of several analytical lines and comparison lines for each element being determined, which can significantly increase the reliability of the results of quantitative analysis;
• allows you to quickly build calibration characteristics based on multiple regression, as well as taking into account inter-element effects;
• allows you to include accounting for dilution of the base;
• provides for one- or two-point recalibration of calibration characteristics, both in the direction of intensities and in the direction of concentrations, as well as to carry out a typical recalibration by concentration;
• allows you to quickly create and change measurement procedures for various samples.
• allows you to keep a measurement log, create reports on the results of measurements and transfer data in the form of a table.
