2.2.25. ABSORPTION SPECTROPHOTOMETRY, …
EUROPEAN PHARMACOPOEIA ABSORPTION spectrophotometry , ultraviolet and visible IMPURITIES IN GASES. For the analysis of impurities, use a cell transparent to infrared radiation and of suitable optical path length (for example, 1-20 m). Fill the cell as prescribed under Gases. For detection and quantification of the impurities, proceed as prescribed in the monograph. 01/2008:20225. ABSORPTION . spectrophotometry , ultraviolet AND visible . Determination of absorbance. The absorbance (A) of a solution is defined as the logarithm to base 10 of the reciprocal of the transmittance (T) for monochromatic radiation : Figure Typical spectrum of polystyrene used to verify the resolution performance T = I/I0 ;. Verification of the wave-number scale.
2.2.25. Absorption spectrophotometry, ultraviolet and visible EUROPEAN PHARMACOPOEIA 6.0 permitted tolerance is ± 1 nm for the ultraviolet range and ± 3 nm for the visible range.
