The flow regulator consists of the following parts: Body. It includes a connector for connection to the control controller and fittings for connecting the input and output gas lines. Calorimetric converter. Due to the heating of the gas along the flow section, the temperature difference is determined. The actuator (solenoid valve). The control board. A system of elements responsible for converting the signals that the user submits. TECHNICAL CHARACTERISTICS OF RD The gas pressure at the inlet is (0.4 + 0.04) MPa. Ranges of working gas flow rates — from 5 to 800 ml/min. The ability to specify the type of gas (nitrogen, helium, hydrogen, argon, air). Pressure ranges — from 0.001 to 0.40 MPa with a discreteness of 0.0001 MPa. The deviation of the carrier gas flow rate from the average value is + 1.5% in the flow range from 50 to 100 ml/min and + 0.5 ml/min in the flow range from 3 to 50 ml/min. Relative deviation of the average steady-state gas flow rate from the set value in the range from 3 to 100 ml/min: + 2.5%, but not less than 0.5 ml/min; from 100 to 200 ml/min.: + 5%; from 200 to 800 ml/min.: + 10%. The gas pressure at the inlet is (0.4 + 0.04) MPa. The deviation of the regulated output pressure of the regulator from the set value is not more than 1%.

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.

The dispenser "DAZH 4000" is designed for automatic insertion of liquid samples into the evaporator of the gas chromatograph, provides: control from the software, setting variable parameters of algorithms for washing and sample entry, storing the operating parameters of the dispenser in the method. Technical characteristics: The number of vials in the carousel, pcs up to 30 The volume of installed vials, ml 0.1-2ml Number of injections from one vial 1-99 Replaceable syringes in volume, ml 10, 100, 250, 500 The volume of the injected sample, ml : from 0.01 to 500 The discreteness of setting the sample volume, µl: from 0.01 to 1 Sampling and insertion rate, µl/s: from 0.01 to 5000 The speed of needle insertion into the evaporator, discret 3 Immersion depth in the vial and evaporator, variable up to the length of the syringe needle, mm 1 – 99 The discreteness of the dive depth setting, mm 0,1 The number of pumping during sampling 0-15 Number of solvent washes 0-15 Needle exposure time in the evaporator, sec 0-99 The discreteness of setting the needle shutter speed, sec 1,0 Sample input modes Simple insertion, Sandwich, Solvent sandwich, Sandwich with internal standard Flushing mode From the vial Supply voltage, V (frequency, Hz) 220 (50) Power consumption, W 154 Weight, kg, no more 2,9 Overall dimensions, mm 175x270x420 Communication with the computer Ethernet

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.
