Microcomputer-based fluorometric kinetic determination of ascorbic acid and flow injection analysis methods for interference correction and kinetic determinations based on the peak profile

Creator:

Chung, Hyung-Keun

Resource Type:

Dissertation
Microcomputer controlled chemical and radiochemical separations and analysis

Creator:

Bennett, Casey Wayne

Abstract:

An automated radiochemical flow analysis (ARFA) system was developed which integrates chemical and radiochemical techniques into one system through the use of a microcomputer. The operator, through the microcomputer, controls valves and pumps to transfer sample and reagent solutions to counting loops, ion exchange columns and holdup reservoirs. A Ge(Li)...

Dissertation
Development of trace enrichment techniques for trace metals in natural waters using high pressure liquid chromatography

Creator:

Ambrose, Arthur Sigurd

Abstract:

An on-line trace enrichment (TE) system, based on high pressure liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has been developed for trace metal analysis. The sample is pumped through a column filled with a cation exchange resin which traps metal ions. The ions are subsequently stripped from the column...

Dissertation
Development of automated on-line ion exchange systems for the determination of chemical speciation of trace metals in natural waters

Creator:

Liu, Yan

Abstract:

An automated on-line ion exchange trace enrichment system has been developed to improve the detection limits of flame atomic absorption (AA) spectrophotometry in the determination of trace metals in natural waters. The sample solution is passed through a column of Chelex-100 chelating resin by a carrier buffer stream delivered from...

Dissertation
Design, construction and application of an instrument for simultaneous measurement of molecular fluorescence, absorbance and chemiluminescence

Creator:

Yappert, Marta Cecilia

Abstract:

An instrument was constructed to measure molecular fluorescence (FL) or chemiluminescence (CL) and absorbance (ABS) simultaneously. The lower, middle, and upper portions of the test solution are probed to obtain ABS, FL, and CL data. Optical fibers are used extensively. The ABS and FL or CL spectra are acquired in...

Dissertation
Design and application of a microcomputer automated multielement flame atomic fluorescence instrument

Creator:

Neyzari, Shahrokh Ghaffari

Abstract:

An automated multielement flame atomic fluorescence (AF) spectrometer based on microcomputer control was constructed to determine four elements simultaneously. The instrument employs a multiple exit slit monochromator where the light from various exit slits is directed to a single detector with a mirrored funnel. Each element is excited to fluoresce...

Dissertation
Application of flow injection analysis to enzymatic fluorescence kinetic methods

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...

Dissertation
A microcomputer automated anodic stripping voltammetric analyzer for trace heavy metal speciation

Creator:

Dewald, Lamar Robert

Abstract:

An automated instrument based on a single-board microcomputer was developed for use in voltammetric analyses. Operator input of numerous experiment parameters allows any type of voltammetric analysis to be implemented and multiple scans to be run unattended. A three operational amplifier potentiostat is used to control the cell voltage and...
