FIELD: physics.
SUBSTANCE: invention relates to a fluid analyzer, in particular to a flow system comprising a fluid transfer system to and from a measurement region, and more particularly, to a liquid analyzer configured to generate transmission and / or liquid reflection spectra in the mid-infrared region that are used in the liquid composition analysis. Fluid analyzer comprises a sample fluid receiver for immersing into a sample fluid, at least one measurement area and a first pumping module configured to act on the flow of liquid from the sample receptacle towards at least one measurement region. First pressure sensor is provided for measuring the pressure between the sample receptacle and at least one measuring region, and the operation of the first pump module directed to regulate fluid flow in the fluid channels is controlled depending on it.
EFFECT: technical result consists in the creation of a more versatile analyzer suitable for carrying out measurements in various liquids.
