Abstract:
The Audubon Sugar Institute (ASI) has a mission committed to state-of-the-art analytical and research technologies toward the continuing success and expansion of the Louisiana sugar industry. One of its goals is the education of both students and industry professionals in the use of these technologies. This proposal is requesting funds to purchase a Diode Array Detector (DAD) package. Prior research projects undertaken at Sugar Processing Research Institute as an example have used the multi-wavelength capability of such detectors to evaluate color-contributing compounds formed during production of raw-sugar. Current and future research will benefit from the addition of this equipment that can simultaneously observe absorbance at all wavelengths from 190-800nm. This capability would greatly expedite and increase the quality of research projects at the Institute. For example, monitoring absorbance at one wavelength can take one hour; observing the behavior of a system ranging from only 190-300nm, with 5nm resolution, would take 22 hours. Current DADs provide wavelength resolutions <1nm, while providing purity information (and with spectral libraries, unknown identification); this task proves impossible using conventional UV-vis instruments. Increased speed and data quality will greatly enhance the quantity and quality of original research at Audubon Sugar Institute. The results of this enhancement project will be of benefit in stimulating more innovative research, extending the scope of potential research projects, improved education and technology transfer. The instrument will be available for both students and faculty at Audubon Sugar Institute to conduct research and extension work.
