(spectroscopy)
A device used in fluorescence spectroscopy to increase the selectivity of fluorometry by passing emitted fluorescent light through a monochromator to record the fluorescence emission spectrum.

Daniel Johnson, Dept, of Chemistry, Murray State University (MSU), allowed us to use the spectrofluorometer.
To determine the amount of tracer injected into the flow that can generate a minimum detectable concentration in the spectrofluorometer and conductivity meter, a simulation was first made using the Gaussian analytic solution of the diffusion-advection equation.
The formation of the reaction product was determined spectrophotometrically as the increase in absorption at 350 nm using an Infinite M200 microplate spectrofluorometer (Tecan, Switzerland).
The steady state fluorescence emission measurements were obtained using a commercially available spectrofluorometer (Fluoromax-2, ISA; Jobin-Yuvon-Spex, Edison, NJ) and spectral band passes were kept as 5 nm in both excitation and emission monochromators.
Luminescence emission and excitation spectra as well as 3D block diagrams were obtained for the three fashioned opals and two of the rough samples using a Horiba Fluorolog spectrofluorometer in conjunction with Fluor-Essence software.
4 mL) from each subsample were placed on a 96-well microwell plate and measured with a spectrofluorometer (Varian Cary Eclipse).
Results showed that very small amounts of this drug could be measured by using the sorbent before pre-concentration process through spectrofluorometer device.
Steady state fluorescence spectra of the bacterial colonies were recorded using Fluorolog spectrofluorometer (Flurolog, HORIBA instruments Inc.
The steady-state fluorescence spectra were taken on a SPEX Fluorolog 3 (Jobin Yvon, Edison, NJ) spectrofluorometer using a continuous 450 W Xe lamp excitation source.
The intensity of fluorescence was measured using a Wallac ArvoSX1420 spectrofluorometer (Perkin Elmer, Waltham, MA, USA) with an excitation/emission wavelength of 485/535 nm as the amount of cells in the each well.
The specimens analysed are urine and plasma (if a spectrofluorometer is available) or feces (if a spectrofluorometer is not available).
