DEVICE FOR SAMPLING AND INTRODUCING SAMPLE Russian patent published in 2024 - IPC G01N30/24 

FIELD: gas analysis devices.

SUBSTANCE: object of the invention is to expand the operational capabilities of the device for sampling and introducing a sample, ensuring its use in measuring equipment intended for detecting and measuring concentration of substances in the atmosphere and in gas mixtures with pressure both above and below atmospheric pressure, while increasing reliability and sensitivity of analysis. Device for sampling and introduction of samples, comprising a dosing valve with a dosing volume, connected to the carrier gas line and to the input of the sampling line connected to the vacuum meter and the cylinder with the analysed gas through the pneumatically operated valve, and the outlet of the sampling line is connected to a vacuum pump through a shut-off valve, which makes it possible to dose samples into the measuring equipment with a given volume and pressure and the possibility of placing a dosing valve with a dosing volume in the thermostat.

EFFECT: broader functional capabilities of the measuring equipment, which is reflected in the possibility of batching gas-vapour samples into the measuring equipment with a given volume and pressure and calibrating the measuring equipment using one calibration gas mixture.
