Virtually all modern chemical instrumentation is controlled by computers. While software packages are continually becoming easier to use, allowing for more researchers to utilize more complex instruments, conveying some level of understanding as to how computers and instruments communicate is still an important part of the undergraduate…

Describes an instrumental analysis experiment that utilizes spectrofluorimetry to determine as little as 0.02 percent glycine in commercial dietetic beverages. (MLH)

Isomeric ketones containing six or seven carbons are separated, illustrating the capability of chemical instrumentation for separating a group of closely related compounds. (MLH)

Describes a unified experiment in which an optically transparent thin layer electrode is used to illustrate the techniques of thin layer electrochemistry, cyclic voltammetry, controlled potential coulometry, and spectroelectrochemistry. (MLH)

The construction of an operational amplifier for use in a chemical instrumentation course is described. (CP)

Presents an inorganic oxidation-reduction kinetics experiment, and describes a low cost (less than $50) modification of the Bausch and Lomb Spectronic 20 Colorimeter which will provide a linear output in absorbance. (MLH)
