Creator:: Prayoonpokarach, Sanchai
Abstract:: A direct purge technique was developed for the determination of chloroform or trichloroethylene (TCE) in water samples. These volatile organic solvents are transferred from the water sample to a reagent where they are trapped and react to form products (Fujiwara chemistry) that are monitored fluorometrically. Chloroform in a water sample...

Creator:: Campi, Gregory Louis
Abstract:: The development and optimization of a fluorometric reaction rate method for the determination of aluminum is described. Modifications to existing instrumentation permit automatic monitoring and reporting of measurement conditions. Automatic correction of measured analytical signals is provided if monitored parameters deviate from optimum values. A computer controlled standard addition procedure...

Abstract:: Improvements in instrumentation for fluorometric kinetic measurements and the application of a new intensified diode array (IDA) rapid scanning system to low level transient fluorescence measurements are reported. This instrumentation is applied to a new fluorometric kinetic method for thiamine (TM). Modifications to the existing fluorometric reation rate instrument include...

Creator:: Prayoonpokarach, Sanchai
Abstract:: A novel, portable, filter fluorometer was developed for the determination of chloroform and TCE at environmentally-relevant levels when coupled with improved sampling techniques and reagents. Reagents selective for the TCE or chloroform convert these toxic species into fluorescent species that can be monitored. The fluorometer is based on LED excitation...

Creator:: Elliott, Colin Bruce
Abstract:: Studies of the use of NADH as the monitored fluorophore for enzymatic fluorescence kinetic methods are discussed. Interference studies for the detection of NADH and the adaptation and optimization of fluorescence kinetic measurements to four serum assays are also described. A microcomputer-controlled flow injection analysis (FIA) system was designed and...

Abstract:: A fiber optic fluorometer utilizing a double-fiber optic probe was constructed. The absolute fluorescence signal and effective collection efficiency are approximately one fifth those of typical cuvette fluorometers and agree with those predicted by theory. A quinine sulfate calibration curve shows linearity from a detection limit of 10 pg/mL to...
