Described is a program in which students learn about spectroscopy and instrumentation to solve a chemical forensic mystery. Infrared and nuclear magnetic resonance (NMR) spectroscopy, refractometry, and chromatographic techniques were used. An example of a mystery case is included. (KR)

Presents a model system designed for the electrophysiological investigation of single unit activity in intact anaesthetized animals. Illustrates how information is coded into action potential patterns by sense organs. Uses the ampullary electroreceptor of the brown bullhead catfish as an example. (Author/CW)

Reported are the results of a survey conducted to identify which analytical methods are most commonly used in nonacademic analytical laboratories. Laboratory supervisors' ratings of various aspects of chemical education are included. (CW)

Describes a technique for separating samples that range over 15 orders of magnitude in molecular weight. Discusses theory, apparatus, and sample preparation techniques. Lists several types of field-flow fractionation (FFF) and their uses: sedimentation FFF, thermal FFF, flow FFF, electrical FFF, and steric FFF. (ML)

Identifies a common laboratory problem that causes instrumentation malfunction. Provides numerous experiences of researchers whose results have been affected by humidity fluctuations, magnetic field fluctuations, trucks driving by, and other factors. (ML)

Announces the incorporation of a laboratory information management system (LIMS) into the academic environment. Describes the applications of a computer-automated laboratory system at one university.
