ˌspectrofluoˈrimetry
Also -fluoro-.
[f. spectro- + fluoro-, fluorimetry.]
The spectrometric study of fluorescence. So ˌspectrofluoˈrimeter (-fluoro-), a spectrometer designed for this; ˌspectrofluoriˈmetric (-fluoro-) a., -ˈmetrically adv.
1957Analyst LXXXII. 611 The sensitivity of the spectrofluorimeter depends not only on the sensitivity of the detector and the intensity of the exciting light, but also on the slit width and aperture of the analysing monochromator. 1961Analytical Chem. XXXIII. 1362/1 The spectrofluorometer has a sensitivity equivalent to 0·01 p.p.m. of quinine sulphate. 1962Lancet 26 May 1130/1 The plasma was analysed spectrofluorometrically for the pharmacologically active spirolactone. 1965Analytical Chem. XXXVII. 137/1 (heading) Spectrofluorometric determination of submicrogram amounts of aluminium and beryllium. 1965Jrnl. Clin. Path. XVIII. 375/1 (heading) A device for spectrofluorimetry. 1971Nature 2 July 24/2 All the chromosomes in the human complement can be paired by these patterns, which can be analysed most accurately by a quantitative spectrofluorimetric method. 1975D. H. Burrin in Williams & Wilson Biologist's Guide to Princ. & Techniques Pract. Biochem. v. 147 Spectrofluorimetry is most accurate at very low concentrations. Ibid., Spectrofluorimeters enable the utilization of great spectral selectivity since..two monochromators may be used.
1957N.Y. Times 8 Nov. 33/4 In the meantime, using spectrofluorometry, thin-layer chromatography and a third technique with iodine, the Coast Guard and the E.P.A. conducted 741 tests at its laboratories in Georgia and Connecticut. 1976Nature 16 Sept. 242/2 The amine was isolated by ion-exchange chromatography..and estimated spectrofluorimetrically. |
