Molecular Fluorescence Measurements with a Charge-Coupled Device Detector.
Abstract
A novel fluorescence spectrometer is described using a two-dimensional charge-coupled device as the detector and a mercury pen lamp as the excitation source. The fluorescence spectra and intensity of anthracene in ethanol standards at concentrations ranging from .0001 to 10 to the -11th power M are shown. The limit of detection measured is 10 to the -12th power M, or 227 parts-per-quadrillion. The linear dynamic range obtained with this instrument is 6 orders of magnitude with excellent linearity using 10 second signal integration time. Keywords: Charge coupled device; Molecular fluorescence; Multichannel detectors; Charge transfer device; Anthracene; Rayleigh spectra; Raman spectra.
