ATOM-ABSORPTION SPECTROPHOTOMETER, ATOMIZER AND ILLUMINATING DEVICE Russian patent published in 2006 - IPC G01J3/42 

FIELD: measurement engineering.

SUBSTANCE: spectrophotometer has the following units mounted in the same case: atomizer, illuminating unit, measurement unit, control unit which has group of outputs connected with gas-distributing unit and with inputs of power supply. The latter is provided with additional input connected with additional output of control unit. Case is made in form of members insulated from each other. Atomizer has mixing chamber, washer of burner, sprayer. Cavities are made between internal and external surfaces of chamber; fitting members are mounted inside the cavities. Illuminating unit has line discrete spectrum radiation source, continuous spectrum radiation source and radiation flux forming unit. The later is made in form of optical elements and devices for correcting disposition of optical axes of radiation sources.

EFFECT: improved truth of results of measurement.
