The FGH-1-2 chromatographs have retained the main advantages of the FGH-1 model – mobility and ease of operation and maintenance. At the same time, FGH-1-2 has all the advantages of a modern multichannel chromatograph – the ability to reliably identify and accurately determine the concentrations of various pollutants of environmental objects. The additional use of automatic identification in the processing of chromatograms simultaneously through both channels makes FGH-1-2, in fact, a universal selective gas analyzer of organic substances using the chromatographic separation method. In FGH-1-2, as well as in FGH-1, all methodological problems have been solved: all measurement methods (MI) used are certified, the devices are equipped with sampling devices prescribed in MI, the devices are graded according to the required substances, independent control of the stability of calibration characteristics and measurement errors is provided.

The highly sensitive HICMOS digital camera manufactured by Abisens LLC is used to register weak light signals, including bioluminescence, in real time, with a photon counting function and visualization of the signal accumulation process in real time (you do not need to wait for the end of the exposure time to see the light signal accumulated by this moment). It is used as a component of high-tech laboratory equipment for scientific research, including installation in the fluorescence and bioluminescence imaging System in LumoTrace® biological samples manufactured by Abisens LLC.

KOIDZ-VD kits consist of samples of artificial defects (SAD) and samples of gaps (SG). Samples of artificial defects are made in the form of flat and curved plates and cylinders, on the working surfaces of which defects are made in the form of continuity violations like slits of various depths, opening widths and lengths. The working surfaces of flat SADs are two opposite surfaces on which longitudinal slits are cut by an electroerosion method The working surfaces of the SAD, reproducing a positive curved surface, are samples with a cylindrical surface. The working surface of the SAD reproducing negative curvature is the inner surface of the curved plate — the place of inflection. The KOIDZ-VD kit contains an SAD for determining the influence of various quantities. To determine the effect of the roughness of the working surfaces, the kit contains SADs with different roughness, on which defects of the same depth are made. To determine the effect of positive curvature and surface roughness, the kit contains cylindrical samples with different roughness of working surfaces on which defects of the same depth are made. To determine the simultaneous effect of negative curvature and surface roughness, the kit contains curved plates on which two defects of the same depth are cut, one of which is located on the flat, the other on the curved parts of the sample. To determine the effect of the chemical composition of the material of the controlled products, the kit contains samples of steel 10, steel 20 and steel 45. The same defects are made on each sample. To account for the influence of specific electrical conductivity, the kit contains samples from non-magnetic structural materials: aluminum alloy D16T and titanium alloy VT-23. The same defects are made on each sample. Gap samples are flat and curved plates of different thicknesses made of dielectric material.
