STUDY OF THE ESTIMATION OF CERTAIN TRACE IMPURITIES BY FLUORIMETRIC METHODS. PART 2.
Abstract
The more sensitive reagents for aluminum at present appear to be the formylhydrazones of resorcylaldehyde or salicylaldehyde and for magnesium, bis-salicylidene ethylene diamine (see AD-603 512). Further work was carried out on the benzoin-mannitol reagent for silicon. The excitation and emission spectra of the metal chelates of many reagents were plotted on the fluorimeter. True spectra were recorded, i.e. quanta per unit frequency interval, against frequency. A fluorimeter was specially developed to carry out this work on true spectra, to facilitate accurate comparison and the international exchange of information. Many aspects of fluorimeter design are discussed. (Author)
