The Europolitest company continues to release its "bestseller" cultivator KVM-05. This cultivator was developed and produced jointly with the Candidate of Biological Sciences prof. Grigoriev and LLC "Omikron", LLC "SFU-System" Krasnoyarsk. Since 2021, due to the reorganization of the production chain, the production of cultivators of the KVM series has been established by Europolitest LLC in the mode of a full production cycle. The thermophilic strain of chlorella algae has been widely used in ecocontrol laboratories, biotests with this test object are by far the most automated biotests that allow reducing time at all stages of work (building up the uterine culture, sample exposure in the biotest, registration of the test function). Cultivator KVM-05 is a long-lived among cultivators of this purpose and a standard of reliability, reproducibility and durability.

The gas distribution panel (hereinafter referred to as the panel) is designed to connect gas nodes and blocks of various analytical instruments, including chromatographs to shop gas lines. technical specifications Inlet pressure, not more than 0.8 MPa. The output pressure is from 0 to 0.4 MPa. Gas flow rate through each channel, not less than — 1000 cm3/min.

The metering valve for the introduction of gas samples is designed for the introduction of gas under excessive pressure into the chromatograph. Cranes differ in the number of moves (4, 6, 8, 10, 12) and have two provisions "Selection" — "Analysis". In addition to dosing, cranes can be used to switch chromatographic columns, elements of gas circuits, etc. The tap can be installed either on the side panel of the chromatograph, or directly into the analytical module instead of, or together with the evaporator of the chromatograph, while it is used as a back-purge tap or for hot sample entry. Additionally, the tap for hot entry can be equipped with heated pipelines. technical specifications The dose volume is from 0.25 to 5.0 ml (at the request of the consumer, the dose volume can be increased to 10 ml and reduced to 0.1 ml). The maximum temperature of the tap is no more than 160 °C. The pressure in the crane line is not more than 0.48 MPa. The angle of rotation of the crane handle — depending on the number of strokes.

To switch the nozzle columns, conventional taps (reverse purge, 6-, 8- and 10-port) are used, which, however, are not suitable for switching capillary columns. An alternative way to switch capillary columns is to change the flows in the capillary columns, which is produced by the so-called "Dins switches" (PD). TECHNICAL CHARACTERISTICS of PD The switching time setting range is from 0.1 to 999 min. Switching time is 0.1 s. The dead volume of the crane is less than 1 µl. The temperature of the tap is no more than 350 °C. The pressure in the crane line is not more than 0.4 MPa. Electric power supply — 5 V.

Selective detector for phosphorus and organosulphide compounds. It is used mainly for the analysis of sulfur-containing substances (hydrogen sulfide, mercaptans, thiophenes, etc.). The sensitivity for sulfur reaches 0.1. ppm. In addition, PFD has sufficient sensitivity and selectivity to compounds containing nitrogen, boron, tin, chromium, selenium, germanium, as well as CO, POPS, MgOx, $02, Ma, NOT C52. The selectivity of 5-containing compounds to hydrocarbons is 105. Technical characteristic: 8,0*10-13 g5/s by sulfur 1.0*10`13 g/s for phosphorus

Selective detector for organochlorine compounds and other halogens. It is also sensitive to compounds containing oxygen, phosphorus or aromatic rings, but to a lesser extent. Paraffins and simple hydrocarbons almost do not capture electrons and are not registered. The selectivity to hydrocarbons is 108. It is available in two versions — conventional EDD and micro-EDD, mainly for capillary columns (the second version is characterized by increased sensitivity). The level of fluctuation noise is up to 300 MV, the maximum signal is up to 5 V, the design of the ECD allows the use of argon, helium, and hydrogen as a carrier gas, in addition to nitrogen. Technical characteristic: 4.0*10-15 g/s for lindane

When determining the total gas content (air) and humidity of transformer oil, direct injection of transformer oil into the evaporator of the chromatograph is used. The sample volume is up to 25 µl, the evaporator temperature is 250-350 °C. The main problem with such an input is the protection of the chromatographic column from transformer oil. For this purpose, a special evaporator is used with the possibility of oil accumulation at the bottom of the evaporator and its subsequent discharge, and a replaceable pre-column that protects the column from oil residues that have passed the evaporator. technical specifications The volume of the evaporator is 10 ml. The number of replaceable pre—columns in the device kit is 5. The temperature of the evaporator is from 250 to 350 °C. The possibility of draining the transformer oil accumulated in the evaporator.

Selective detector for organophosphorus and nitrogen compounds. It is also sensitive to compounds containing C, Az, but to a lesser extent. The sensitivity depends on the number of heteroatoms in the molecule. Selectivity to hydrocarbons is 104 for nitrogen, and 105 for phosphorus Technical characteristic: 2.0*10-13 m/s nitrogen 1.5*10`14 g/s for phosphorus

It operates in the mode of a helium ionization detector (GID) and is considered the most sensitive device for determining permanent gases. In addition, it is able to work in the EDD mode. Technical characteristic: 2.0*10`13 g/s by. methane or hydrogen

It can be used as a primary source of carrier gas, since it is equipped with an additional gas purification system. This device is especially relevant when, for some reason, helium is not available to the consumer (for example, when working with a thermal conductivity detector - an accident). Due to the high thermal conductivity of hydrogen, TTP operates with significantly greater sensitivity than helium.
