Abstract Details

2017, Master of Science, Miami University, Chemistry and Biochemistry.
This thesis describes two unique projects that involve the investigation of low-cost molecular spectroscopy and microscopy instrumentation. This investigation was performed using both existing spectroscopic instrumentation and those constructed in the laboratory. The first project entailed building a custom Raman spectrometer using a low-light level monochrome digital camera as a detector to see if improvements could be made over another homebuilt Raman spectrometer which utilized a commercial digital photographic camera. The second project involved a comparison of infrared instruments from different periods in time and the investigation of the new SurveyIR microscope accessory that can be placed directly into an FTIR sample compartment. Results for the first project demonstrated that incorporation of the lowlight level camera as a detector into the lab constructed Raman spectrometer provided no major advantages over the commercial digital camera. Results for the second project showed that while older instruments and accessories could potentially be used for certain applications, newer instruments and accessories provided notably higher light throughput and signal to noise values. For both light throughput and signal to noise, the highest values were achieved using the SurveyIR microscope interfaced to a Frontier FTIR. The SurveyIR was also able to utilize its ATR functionality to reproduce the quantification of pigments in pigment loaded polypropylene fibers which had previously been performed using transmission infrared techniques
