A Stopped-Flow Analyzer for Kinetic Methods Development - Automated Implementation of Guggenheim's Methods
Accessories have been designed and constructed which directly transform a conventional single-beam spectrophotometer into a versatile stopped-flow kinetic analyzer. A relatively inexpensive microcomputer system serves as a dedicated controller/data processor for the instrument. The design employed features preservation of the optical configuration and geometry of the original spectrophotometer. Thus, abilities related to the performance of precise, absolute absorbance measurements have been retained. Additionally, kinetic response curves can be reproducibly generated, primarily due to efficiencies on solution transport and mixing components built into the "stopped-flow module". The hybrid nature of the instrument, allowing reliable collection and processing of responses from both kinetic and equilibrium phases of reactions, is seen as a powerful attribute.
