CRYOCONCENTRATION DEVICES
CRYOCONCENTRATION DEVICES
To determine small concentrations of substances, in some cases it is impossible to do without their concentration in special traps. An example of the need for such concentration is the determination of impurities in permanent gases (Ne, He, H2, Ar, O2, N2, Kr, Xe), the concentration of impurities is less than 1 ppm. Considering that these impurities can be not only hydrocarbons, but also permanent gases themselves, the use of direct detection of impurities by a catarometer is impossible. It is also not always possible to use highly sensitive but expensive detectors (GID, EDD, etc.). TECHNICAL CHARACTERISTICS The volume of the trap is 5 ml. The volume of the Dewar vessel (serial metal thermos) is 1200 ml. The concentration temperature range is from minus 88.6 (ethane) to minus 269 °C (helium). The ability to calibrate the chromatograph from the cylinder without disturbing the gas circuit. The possibility, simultaneously with concentration, to purify the gas intended for purging the trap from impurities (in a similar trap). Overall dimensions, no more than — 290 ×470 × 615 mm. Weight, not more than — 8 kg.

KOIDZ-VD Sets of samples of artificial defects and gaps
KOIDZ-VD Sets of samples of artificial defects and gaps
from 0 ₽
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.
