19. Spectral Evaluation

20. The Beer-Lambert Law The relationship between the absorbed light and the number of molecules in the path. Absorbed Light is Directly Propotional to the Concentration

21. Span and Zero Calibration – CEM Calibration bench Analyser Standard gas Calibration cell Power supply Receiver Emitter

22. Calibration (C p x L p = C c x L c ) C p= Concentration in the measuring path L p= Length of the measuring path(/diameter) C c= Concentration in the cell (=gasbottle) L c= Length of the Calibration Cell Example: 100 ppb x 500 m = 1000 ppm x 0,05 m “ Optical density”
