The Margerum research group is a vital part of the Analytical Chemistry division at Purdue because of the wide variety of techniques used to conduct our research as well as the past and present need to develop new instruments to solve problems.
Spectrophotometers encompass the majority of the instruments in our lab.
Elmer Lambda 9 scanning instrument. This instrument is particularly useful because its operation is fully automated. These instruments are capable of measuring reactions that are too fast for the stopped-flow techniques. The PAF method integrates observation with continuous flow mixing over a decelerated velocity profile. Rate constants for these fast reactions can be abstracted from the data by mathematical analysis.
