Abstract: An improved atomic fluorescence spectrometer in which good correlation between output signal and concentration of sample is achieved by providing a dual channel biomodal detection system for the detection of modulated signals. This detection system provides means to allow for scattered light intensity as well as non-fluorescent emitted light. An improved method of detection of square or approximately square modulated signals allows information to be derived from the signals during up to 80 percent of elapsed time. Attachment of memory means with arithmetic capability allows automatic processing of output data.
