Spectroanalytical tripod "Globula"

The installation is designed to excite atomic emission spectra of powder samples in an electric arc by the spillage-injection method. It provides high performance of routine analyses, has a low consumption of graphite electrodes and is used in conjunction with any spectral devices – "Grand", STE-1, DFS-458, MFS-8, PGS-2, etc.

A remote-controlled atomizer of powder samples with automatic change of revolver-type samples with arc excitation of the spectrum. It consists of an automatic tripod "Carousel" for arc spectral analysis and a spectroanalytic generator "Ball Lightning"– 40A fully compatible with the expert software system "ATOM" and the MAES analyzer.

The generator is designed to produce an electric arc and spark discharge in atomic emission spectral analysis installations. The generator is designed specifically for use in spectral analysis of samples of complex composition for simultaneous determination of impurity and alloying components in a wide range of concentrations.

The MAES analyzer is a modern means of measuring the intensities of spectral lines and then calculating the concentrations of the elements to be determined.

The laser source is designed to excite atomic emission spectra when performing qualitative spectral analysis of hard rocks - metals, minerals, glasses and others. The source is based on a two-pulse YAG: Nd laser with electro-optic Q-switching operating at the main wavelength of 1064 nm. The duration of each pulse is no more than 10 ns, and the delay between them is adjustable from 0 to 60 microseconds. The possibility of the laser beam to focus on an area of 300 to 1000 microns makes it possible to conduct microanalysis of inclusions, perform two-dimensional scanning of the surface or locally analyze samples with virtually no damage to the surface. A significant advantage of the laser source is the expressiveness and lack of special sample preparation for a wide range of conductive and non-conductive materials. Visual observation and pointing of the beam at the sample is carried out using a stereoscopic microscope integrated into the system, as well as a high-resolution digital video camera with image transmission to a computer. Moving the instrument table with a fixed sample is possible both manually for adjustment, and with the help of stepper motors in two coordinates during analysis, which provides surface scanning and spectrum recording with reference to the video image. The installation can be used in conjunction with any spectral devices – "Grand", "Aspect", "Express", "Hummingbird-2", STE-1, DFS-458, MFS-8, PGS-2 and others. The laser source is designed to excite atomic emission spectra when performing high-quality spectral analysis of hard rocks – metals, minerals, glasses and others.

A device for preparing metal samples for spectral analysis. For the preparation of metal samples, an emery cloth or paper with a given size and abrasive material is used. The rotation speed is 1500 revolutions per minute. A quick stop of the motor is provided by an automatic control unit. There is a version in a housing made of composite materials with two discs, each can have its own type of abrasive.

The plasmatron is designed for direct atomic emission spectral analysis of powder samples. The excitation of atoms occurs in a DC argon arc plasma. Weak matrix effects and low detection limits make it possible to use this excitation source for the analysis of various samples, both with mineral and organic matrix.
