INSTANTANEOUS READING MULTICHANNEL POLYCHROMATIC SPECTROPHOTOMETER METHOD AND APPARATUS Abstract of the Disclosure A beam of radiation is directed into a liquid sample cell containing a sample to be analyzed in solution. The illumination emanating from the sample cell as a result of the beam of radiation from the radiation source is diffrac- ted into a polychromatic spacially divergent beam and directed to a linear array of photovolta- ic photodetectors with different spectral seg- ments of the beam being intercepted by different photodetectors of the array. The signals from the photodetectors are separately and substantial- ly simultaneously sampled and held to thereby obtain data usable for a high-accuracy wide- spectrum chromatogram.
