A silicon-intensified target vidicon is evaluated as a detector for synchronous fluorescence spectroscopy. Data acquired in the form of 180 emission spectra at each of 100 excitation wavelengths are stored in computer memory. Synchronous spectra are obtained as diagonals through the data matrix that correspond to fixed wavelength differences (Δλ) between excitation and emission wavelengths. Single- and two-component mixtures of anthracene, 9,10-diphenylanthracene, perylene, and tetracene were studied. Of the possible mixtures, synchronous spectra for three exhibited no detectable interactions; spectra for two exhibited one-way interactions; and spectra for one exhibited two-way interactions. Relative pooled standard deviations were in the range of 1% for single-component samples and 4-8% for two-component samples. Detection limits at the 95% confidence level were estimated between 0.005 mg l-1(perylene) and 0.17 mg l-1(anthracene). © 1983.
