Using fourier transformation methods in nuclear magnetic resonance has made possible increased sensitivity in chemical analysis. This article describes these methods as they relate to magnetization, the RF magnetic field, nuclear relaxation, the RF pulse, and free induction decay. (CW)

Describes a program to provide a major improvement in the national instrumental analysis capability of Chinese universities and associated industries. Notes the network ended its first five years of operation with a sense of accomplishment, but found its perspective much different than at the startup. (MVL)

Addresses solution nonmetal determinations on a fundamental level. Characterizes research in this area of chemical instrumentation. Discusses the fundamental limitations of nonmetal atomic spectrometry, the status of nonmetals and atomic spectroscopic techniques, and current directions in solution nonmetal determinations. (CW)

Describes use of a Fresnel biprism to demonstrate double-slit interference with polarized light. Discusses polarization and phase properties of a randomly polarized gas. (JM)

Describes an advanced high school chemistry course that exposes students to a wide variety of modern, realistic instrumental techniques. The laboratory syllabus for the course (which uses the textbook "Organic Chemistry" by Morrison and Boyd) is included. (JN)

Biology teachers at Ithaca College have developed a course in experimental methodology and instrumentation that teaches beginning biology students the need for accuracy and precision in measurement. This course is described. (JN)

Reports results of a survey of college professors (N=146) on the present use of chemical instrumentation in undergraduate chemistry curricula of four-year colleges and universities in the United States. Uses in general, organic, analytical, physical, integrated, and research chemistry courses are noted. (JM)

Describes an experiment designed to acquaint students with the theory and applications of anodic stripping voltammetry (ASV) as well as such ASV problems as contamination associated with trace analysis. The experimental procedure, instrumentation, and materials discussed are designed to minimize cost and keep procedures as simple as possible. (JM)

Presents an experiment in thermometric titration used in an analytic chemistry-chemical instrumentation course, consisting of two titrations, one a mixture of calcium and magnesium, the other of calcium, magnesium, and barium ions. Provides equipment and solutions list/specifications, graphs, and discussion of results. (JM)

Reviews a noncommercial educational game (Polymerlab) and changes made in GASLAWS (adaptation of mainframe program used in computer-assisted instruction). Describes programs on simulation of molecular speed distributions; interfacing microcomputers to make laboratory measurements; a course in microcomputer-instrument interfacing and measuring and…

Four ways in which microcomputers can be turned into laboratory instruments are discussed. These include adding an analog/digital (A/D) converter on a printed circuit board, adding an external A/D converter using the computer's serial port, attaching transducers to the game paddle ports, or connecting an instrument to the computer. (JN)

Discussed are two techniques that can be used to directly test the theory that the plates which make up the crust of the earth are still moving. Described are the use of satellite laser ranging and very long baseline interferometry. Samples of data and their analysis are provided. (CW)

Greater access to scientific instrumentation, courses, and supporting materials through the Internet and Integrated Laboratory Network (ILN) has the potential to profoundly change the way in which instrumental sciences are taught. Increased access to instrumentation will provide better opportunities for students to learn and practice instrumental…

This guide defines a methodology for program monitoring and discusses positive results achieved in Pennsylvania by implementing Instrument-based Program Monitoring (IPM) in the field of child day care services. IPM uses checklists or special questionnaires to structure monitoring interviews and site visits. This method differs substantially from…

Discusses functions of automated instrumentation systems, i.e., systems which combine electrical measuring instruments and a controlling computer to measure responses of a unit under test. The computer-assisted tutorial then described is programmed for use on such a system--a modern microwave spectrum analyzer--to introduce engineering students to…
