Presents a low cost system with easily replaced electrodes for use in general chemistry. Notes the accuracy and wide applicability permit easy use in physical or quantitative chemistry experiments. Provides schematic, theory, and helpful suggestions. (MVL)

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)

Examines two computer interfaced lab experiments: 1) discusses the automation of a Perkin Elmer 337 infrared spectrophotometer noting the mechanical and electronic changes needed; 2) uses the Gouy method and Lotus Measure software to automate magnetic susceptibility determinations. Methodology is described. (MVL)

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)

Discussed are four major advantages to the use of microscale laboratories for teaching chemistry. Included are effects on waste generation, laboratory safety, reagent variety, and laboratory efficiency. (CW)

Notes the careful observation of chemical reactivity phenomena has been and should be an important part of the general chemistry laboratory curriculum. Stresses reduction of experimental scale will help to ensure, in times of rampant chemophobia, that it remains so. Provides several examples of the methodology. (MVL)

Develops a compact minicell design in which the measured voltage is close to the desired emf. Notes student's observations for several cells are within 0.02V of the expected values. Presents numerous reasons for using miniware and semimicro qualitative analysis. Full experimental writeup is available from the authors. (MVL)

Discusses the use of robotics in the analytical chemistry laboratory. Suggests using a modular setup to best use robots and laboratory space. Proposes a sample preparation system which can perform aliquot measurement, dilution, mixing, separation, and sample transfer. Recognizes attributes and shortcomings. (ML)
