The principle of operation of the electronic diaphanoscope YANTAR is to assess the vitreousness of the image obtained using a digital camera. The vitreous value is calculated using a software-implemented algorithm using special calibration equations. The analysis time is 1 minute. Automation of the vitreous assessment avoids the error associated with the subjective opinion of a specialist. The use of specially developed calibration standards based on optical filters for uniform adjustment of diaphanoscopes permits to coordinate the operation of two or more devices remotely. The interlaboratory error in determining the vitreousness on the devices included in the network does not exceed the standard. All the results of the determination of the vitreousness of wheat with the corresponding grain images are stored in the archive. If necessary, specialists can print the protocols of the current or any of the previous definitions. THE ALGORITHM OF OPERATION: 1. Pour the grains into the cassette and close the lid made of transparent glass. 2. Install the cassette in the diaphanoscope. 3. Launch the program. 4. Choose a product 5. Software processing of the digital image of grains in accordance with the selected product 6. Calculation of computer results. In 2023, a new national standard GOST R "Wheat. Determination of vitreousness by optical-computer method".

The reverse purge valve is a 4-way valve designed to change the direction of the flow of the eluent through the nozzle column and blow off heavy components from the beginning of the column in the opposite direction into the detector. The crane is attached to the bottom panel (bottom) of the module, while taking the temperature of the column thermostat. The two upper fittings (see Fig.) are used to connect the column, the other two are connected to the evaporator and the detector.

The metering valve for the analysis of liquefied gas (KDSG) is designed for the introduction of liquefied gas or other liquid under excessive pressure into the evaporator of the chromatograph. KDSG is a 4-way crane, in which a dose of a certain volume is installed. The tap is installed on the evaporator of the chromatograph. A dose of any volume can be installed on the tap. Dose change can be performed by the operator. The amount of the dose volume is indicated on the tag. Technical specifications The dose volume is from 0.25 to 4.0 µl (at the request of the consumer, the dose volume can be increased up to 10 µl). The tap temperature is no more than 150 °C. The pressure in the crane line is not more than 0.48 MPa. The angle of rotation of the crane handle is 90 °C.

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.

The pyrolytic gas chromatography method is widely used in the study of polymer materials, plastics, rubbers, rubbers, paints and other high-molecular compounds of natural and artificial origin. The method is based on thermal decomposition of sample samples in an inert medium (without oxygen access), followed by chromatographic separation and analysis of the formed volatile compounds.

The principle of operation is based on measuring the zonal reflection coefficient of a compacted-smoothed flour surface using a built-in standard. The laboratory white meter BARS is approved as a type of measuring instruments and is registered in the State Register of Measuring Instruments under No. 78409-20. All manufactured devices undergo primary verification and have the appropriate certificate. Due to the two-channel design of the device (the presence of two photometric units and a cuvette with two cells), parallel measurements of the whiteness of one flour sample are carried out simultaneously, the average value is calculated automatically, which significantly reduces the time of analysis. The sealing of the flour sample with a fixed force and pressing against the optical windows ensures the same measurement conditions and eliminates the influence of a subjective factor on the result. The automatic adjustment system based on the built-in standard allows to ensure long-term stability of the device without the need for manual adjustment. During operation, the standard is set to the working position by an additional drive. Mechanical damage or loss of the standard is excluded. The output to the operating mode is no more than 30 seconds. The determination of whiteness is carried out in 15 seconds. To determine the whiteness of flour, the operator needs to fill 2 compartments of the cuvette with the test sample of flour, install the cuvette in the device and start the measurement process. All the results of the whiteness definitions are stored in the archive. The operator has the opportunity to view the electronic measurement log.
