A gas chromatography (GC) mass spectroscopy (MS) system recently developed by Hewlett-Packard (HP-5987 GC/MS/Data System) is described, illustrating the technological advances that have been achieved with the system. Examples of the data processing and output process are provided to demonstrate the capabilities and application of the system to…

Discusses problems and pitfalls of working with single-pan balances and methods used to advertise their accuracy. Investigated manufacturers knowledge of buoyancy effects, relating provisions and recommendations made by various companies. Provides a routine for intercalibration of weight using dummy weights of approximately known mass. (JM)

Describes an experiment designed to teach students to apply the same statistical awareness to instrumentation they commonly apply to classical techniques. Uses propagation of error techniques to pinpoint instrumental limitations and breakdowns and to demonstrate capabilities and limitations of volumetric and gravimetric methods. Provides lists of…

Uses of Zenith Z-100 microcomputers by chemistry students at Clarkson College are discussed. These include: (1) programing; (2) word processing; (3) numerical methods, statistical/plotting programs; (4) laboratory data acquisition and manipulation; (5) simulations; (6) computer assisted instruction; and (7) computer managed instruction. (JN)

The authors state that organizational development (OD) consultants are reluctant to rely upon instruments because this would diminish their sense of usefulness. They discuss 15 OD issues and conclude that OD instruments must be based on sound principles of behavior and sequenced in a planned way in order to implement organizational change and…

Describes a photochemistry experiment designed to introduce photochemical techniques and experience free radical chemistry. Selects Nuclear Magnetic Resonance spectroscopy for the analysis. This activity is suggested for use in an upper level undergraduate organic course. (MVL)

Identifies the properties and characteristics of supercritical fluids. Discusses the methodology for supercritical fluid chromatography including flow rate, plate height, column efficiency, viscosity, and other factors. Reviews instruments, column types, and elution conditions. Lists supercritical fluid data for 22 compounds, mostly organic. (MVL)

One of the traditional problems in courseware development that is recognized as hard to solve, is the communication and co-operation between various disciplines in project teams that are working on a courseware product [Alber (1996) "Multimedia: a management perspective." California: Wadsworth; Boyle (1997) "Design for multimedia learning." UK:…

In the study of perception during reading, the use of eye movement contingent control of the stimulus display has proved to be a useful research technique. With such a system, it is possible to experimentally manipulate, in real time, the characteristics of the stimulus display that is present on selected fixations as reading is in progress and to…

Avocational counseling is defined as helping people to choose meaningful leisure activities. The author describes instruments for assessing avocational interests, discusses various procedures used during avocational counseling and describes target groups which might benefit from such counseling. Various attitudes toward leisure held by different…

Scientists/engineers from industry, universities, and government met to: review the status of scientific instrumentation in university research laboratories; explore new approaches to alleviating problems within existing budgetary constraints; and suggest ways for the National Research Council (NRC) to help. Federal agency, corporate, and…
