Method and device for the simultaneous determination of the concentrations of molecular compounds in gases and liquids.

摘要

MEASURING DEVICE ALLOWS SIMULTANEOUS MERGER AND RADIATION ABSORPTIONS multicomponent MIXES WITH HELP FROM RADIATION DETECTOR UNICO located behind the measuring cell with very high accuracy measurement, a long-term stability and low costs. TO SOLVE THE TASK IS PROPOSED IN ACCORDANCE WITH THE PROCEDURE TO BE ISSUED RADIATION THROUGH THE MIDDLE OF DIFFERENT WAVELENGTH WITH DIFFERENT FREQUENCY PULSES AND SPECIFIC SIGNS OF MOLECULES GENERATED IN DETECTOR OF RADIATION be separated by broadband amplifiers NARROW DIFFERENT center frequencies. The device is configured so that the radiation source (40) has THEREAFTER WILLING A CHOPPER (53) SYSTEM OF PARTIAL SYSTEMS STATIONARY (42, 56, 57) AND SYSTEMS PARTIAL Moviles (41, 54, 55) AND RADIATION ( 62,63) are SEPARATED BY NARROW BAND AMPLIFIERS (48, 49) and can continue processing.
