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.

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).

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.

Weight, not more than — 8 kg.

The hydrogen generator is equipped with its own microprocessor, with which you can control the operating modes of the device. It is microprocessor control that determines the autonomy of the device. Moreover, this allows you to control the basic and technical parameters of the device (pressure, flow rate, level of water poured into the tank, tightness of gas lines, electrolyzer current). For the manufacture of gas lines, exclusively inert materials are used. Technical specifications:

The device is equipped with a four-button keyboard, which is used to set parameters and control. The generator can operate in continuous mode for a long time. For refueling, especially pure or double-distilled water is used, and refueling can be done without turning off the device, on the go. Their advantage is that they significantly reduce, or even completely eliminate, the use of bottled gases to power chromatographs and gas analyzers. For nutrition, mainly double-distilled water is used, the quality of which must be no lower than grade B water according to OST 11.029.003–80, and the electrical resistivity must be no less than 1 Mohm x cm.

The devices operate from a single-phase AC electrical network with voltage from 187 to 242 W, frequency (50±1) Hz. Maximum safety of devices is achieved due to the absence of such a supply of substance in them, which could fill a chromatograph or laboratory in a short period of time. The performance of the device eliminates the occurrence of explosive situations, so the generator is considered safe to use.
