Abstract
The construction of an inexpensive SPR instrument that can be used for both teaching and research is described. Using a 2′ × 2′ optical table to construct this instrument allows both scientists and students full access to the operation of the spectrometer. Furthermore, the use of open platform instrumentation has the advantage of maintaining the focus on the relationship between emerging technology and analytical chemistry as well as allowing the user to modify the instrument to enhance the measurement process for a particular application. This is a change from the learning paradigm used in most research and teaching laboratories where commercial instrumentation is treated as a black box due to its complexity. Three studies, which were performed using this instrument, are presented to demonstrate the suitability of this instrument for both teaching and research. These studies include measuring the refractive index of alcohols, investigating the partitioning of ruthenium (II) trisbipyridine chloride into Nafion, and understanding the mechanism controlling metal ion adsorption by polyacrylamide hydrogels.
