SYSTEM FOR WAVELENGTH SPECTRAL ANALYSIS FOR GAS IDENTIFICATION USING TREATED TAPE Russian patent published in 2014 - IPC G01N31/22 G01N21/25 

FIELD: instrumentation.

SUBSTANCE: invention relates to the field of gases identification and refers to a spectral analysis system for gases identification using a treated tape. The system includes a treated tape, an adjustable colour source, a photodiode, a colour identification sensor and a microprocessor. The adjustable colour source emits radiation in the direction of the treated tape with multiple varied wavelengths. The photodiode measures the radiation reflected from the treated tape. The microprocessor analyses the measurement results and, proceeding from the colour identified and the colour spot intensity, identifies the type and concentration of the gas the treated tape has been exposed to. Additionally, the microprocessor, with the help of the colour identification sensor, controls the radiation wavelength of the adjustable colour source and, whenever required, corrects the colour source radiation.

EFFECT: technical effect consists in increased sensitivity and ensuring the possibility of different type gases detection.
