Polylcaprolactone-Based Microfluidic Devices : Fabrication Methods and Applications in Low-Cost Analytical Devices

Creator:: Heist, Christopher A.
Abstract:: The overall concept of reducing laboratory operations to a scale that fits on a single microfluidic chip has been an attractive area of research over the last several decades. Despite a surge in research, few commercial success stories have been written. Lab-on-a-chip technologies have the capability to be cost effective...

A reaction rate determination of aluminum with a microcomputer-based spectrofluorometer

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...

Design and development of an intensified diode array system and its application to new fluorometric reaction rate methods of analysis

Creator:: Ryan, Mary Andrieu
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...

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...

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)...

Application of piezoelectric quartz crystal as partition detector : development of a digital transducer

Creator:: Janghorbani, Morteza
Abstract:: AT-cut piezoelectric quartz crystals coated with low vapor pressure materials are evaluated as digital transducers in completely digital detection systems for monitoring gas streams. Mathematical relations describing the detectors are developed and tested. Specific application is made to monitoring gaseous sulfur compounds commonly found in stack effluents of pulp mills....

Development of automated flow injection apparatus and a novel flow cell for chemi- and bioluminescence determinations

Creator:: Gander, Stuart C.
Abstract:: A practical and versatile instrument has been developed both to optimize the chemistry of bio- and chemiluminescence reactions and to measure ultra-trace quantities of associated analytes. The instrument consists of a pneumatic flow injection system linked to a detection cell and a signal processing and readout system. The disk-like cell...

Multielement atomic absorption and fluorescence spectrometry

Creator:: Salin, Eric Dunbar
Abstract:: A multielement spectrometer has been developed for the simultaneous determination of four elements by atomic absorption (AA) or atomic fluorescence (AF). The spectrometer is based on a multiple exit slit monochromator and uses a mirrored funnel to direct light from the various exit slits to a single photomultiplier. There are...
