What is A Microprocessor-controlled, Multichannel Fluorimeter for Analysis of Sea Water about?
The multichannel fluorimeter described provides good sensitivity and rapid data acquisition. The advantages of multichannel fluorescence detection are discussed with special reference to the continuous monitoring of in vivo chlorophyll fluorescence in sea waters. Experiments on chlorophyll a determinations indicate a detection limit of 5 X lO\_" M with a linear range over at least three orders of magnitudes of concentration. Fluorescence spectrometric techniques are characterized by low detection limits and good selectivity. The detection limit of fluorescence is typically three to four orders of magnitude below that of absorbance. This advantage arises from the direct detection of photons using fluorescence in contrast to the measurement of a small difference in two large photon signals in absorbance. The many parameters of fluorescence spectrometry which can be exploited provide the advantage of excellent selectivity. Emission intensity is dependent on both the wavelengths of excitation and emission. Many fluorophores can be spectrally separated based on these two parameters alone. However, by incorporating other parameters such as fluorescence lifetimes, phosphorescence spectra
