Abstract

1,114,193. Photo-electric analyzers. IMPERIAL CHEMICAL INDUSTRIES Ltd. Sept. 7, 1965 [Sept. 15, 1964; May 17, 1965], Nos. 37623/64 and 20734/65. Heading G1A. In a photo-metric analyzer in which radiation from a single source traverses a single optical path through the sample cell and is received by a single detector, the beam of radiation is divided so that two different wavelengths traverse different paths and then fall alternately on the detector. The beam may be split and recombined before or after passing through the sample. The beam may be split and recombined by a rotating double sided mirror. Figs. 1A, 1B, 4A (not shown)different filters being provided in each path so formed. Alternatively, Figs. 2, 48, 6, 8 (not shown) the beam may be split by mirrors which transmit one wavelength and reflect another, the alternation of the beams being effected by a chopper. In a third form, Fig. 3 (not shown) the splitting may be by semi-transparent mirrors, both filters and a chopper then being used in the two paths. By a suitable arrangement of rotating mirrors or wavelength selective mirrors, Figs. 4A and 4B (not shown), measurements may be made at four wavelengths. The radiation may be modulated at a carrier frequency of say 800 c/s by suitable formation of the chopper, or by provision of an extra chopper at a point where the beam is undivided. A phase reference signal is generated by a lamp and photo-cell co-operating with the main chopper. A diffuser may be provided to spread the radiation over the whole of the detector. Reference has been directed by the Comptroller to Specification 876, 905.
