Dispenser to the device for measuring sulfuric acid

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.

Device for dosing of liquefied gases is made for insertion of liquids and liquefied gases under the pressure of 7 MPa into the chromatograph. Injection of liquefied gas without de-gassing is provided by cooling of valve, and it greatly reduces inaccuracy of the analysis results. Cooling temperature is set by temperature regulator. Visual control of absence of de-gassing and flow control of the analyzed fluid is provided. Dose volume is form 0.2 to 2 mcl. Valve of VICI production or dispenser valve of our own production is used directly as a sample-valve.

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.

The equilibrium steam dispenser "DRP-10 (DRP-13)" is designed for the introduction of volatile components from matrices into the chromatograph, the introduction of which into the chromatograph is impossible or undesirable. Examples of such matrices are natural, drinking and waste water, soil, biological fluids, food and beverages, various polymers, building materials, pharmaceutical products, etc. The use of DRP-10 (DRP-13) makes it possible to avoid contamination of the evaporator, column and chromatograph detector with non-volatile or non-volatile substances, to avoid the consumption of solvent required for extraction, to increase the reproducibility of analyses. Technical specifications The temperature of the thermostat of containers with a breakdown is from ambient temperature to 150 °C. The error of maintaining the temperature is not more than 0.1 ° C. The volume of the container with the sample is 20 ml, it is possible to use vials from 6 to 40 ml. The number of simultaneously thermostatically controlled containers is 4. The dosed volume of the equilibrium vapor is up to 2 ml. The temperature of the syringe is from ambient temperature to 150 °C. The gas consumption for purging is from 5 to 300 ml/min. Electric power supply from the AC network with voltage (220index) V, frequency (50 ± 1) Hz. Overall dimensions (width × depth × height) — 350×270×170 mm. Power consumption — no more than 360 VA. Weight — no more than 6.5 kg.

The dispenser in the Florinsky device serves as a reservoir for reagents, on which 10 pipettes of the appropriate volume are fixed.
