turbidimetry nephelometry 4.0 / 5 based on 1 rating ? BiologyotherOtherNone Created by: une-meduseCreated on: 06-01-15 21:40 from the intensity of light transmitted through the medium, the unscattered light is measured turbidimetry 1 of 19 from the intensity of light transmitted through the medium, the scattered light is measured nephelometry 2 of 19 the scattered light is measured at right angles to the incident beam nephelometry 3 of 19 Scattered intensity = K x initial intensity x concentration nephelometry 4 of 19 transmittance = intensity transmitted / initial intensity turbidimetry 5 of 19 the most common light source used in turbidimetry is tungsten filament lamp 6 of 19 direct measurement - measures the cloudiness of a solution by measuring the amount of light directly passing through a solution turbidimetry 7 of 19 indirect measurement - measures the amount of light scattered by the antigen antibody complexes nephelometry 8 of 19 glass cuvettes absorb ____ uv 9 of 19 quartz cuvettes absorb no radiation 10 of 19 more sensitive diode array 11 of 19 a region in the molecule where the energy difference between two molecular orvitals falls within the coloured region of the em spectrum chromophore 12 of 19 more chromophores compound absorbs at longer wavelength 13 of 19 longer lifetime phosphoescence 14 of 19 when excited an emission obtained only for time of irratiation fluorescence 15 of 19 when excited an emission obtained for longer than time of irradiation phosphoescence 16 of 19 wavelength of fluorescence is of the wavelength of phosphoescence smaller 17 of 19 fluorescence _______ by oxygen/metals quenched 18 of 19 phosphorescence _____ by oxygen completely inhibited 19 of 19
