DEVICE AND METHOD FOR MEASUREMENT OF SPECTRA OF OWN RADIATION OF LIQUID SAMPLES IN INFRARED RANGE AT HIGH PRESSURE Russian patent published in 2022 - IPC G01J3/443 

FIELD: spectroscopy.

SUBSTANCE: invention relates to the field of spectroscopy and concerns a device and a method for study of liquid biological samples at high pressure. The device includes a spectrometer, which provides a possibility of Fourier transform of a signal, a node for cold background formation, a mirror. The device additionally contains liquid thermostat, a node for high pressure formation, a controller, and a unit for processing of spectrometer signals, connected to a computer. The node for cold background formation contains flat thermostat, which is placed under the lower surface of a black plate with the possibility of setting of a temperature of the black plate in the range from -20 to +100°C. A thermostated cuvette provides a possibility of quick adjustment of a thickness of a layer of the studied liquid sample due to change in a distance between optical fibers.

EFFECT: provision of a possibility of highly sensitive spectral analysis of liquid biological samples at high pressure without effect of external radiation.
