Discusses recent developments in the instrumentation and practice of analytical scale operations. Emphasizes detection devices and procedures in gas chromatography, liquid chromatography, electrophoresis, supercritical fluid chromatography, and field-flow fractionation. (JN)

Discusses: (1) rationale for chemical sensors in process analysis; (2) existing types of process chemical sensors; (3) sensor limitations, considering lessons of chemometrics; (4) trends in process control sensors; and (5) future prospects. (JN)

Reviews literature dealing with novel developments or important trends in electrochemistry. Areas examined include mass transfer, electrode kinetics, surface effects, chemically modified electrodes, coulostatic/galvanostatic methods, bioelectrochemistry, spectroelectrochemistry, and electrode instrumentation. Books, textbooks, and literature…

Presented is a review of selected literature on emission spectrometry published during 1982 and 1983. The review is organized under these headings: books and reviews; spectral descriptions and classifications; instrumentation; standards, samples, nomenclature, calibration, calculations; excitation sources; selected applications; and meetings. (JN)

Reviews developments in ultraviolet and light absorption spectrometry from December 1981 through November 1983, focusing on the chemistry involved in developing suitable reagents, absorbing systems, and methods of determination, and on physical aspects of the procedures. Includes lists of spectrophotometric methods for metals, non-metals, and…

Discussed are various types of electronic laboratory balances. (RH)

A variety of materials are described including spectrophotometers, chromatographs, voltmeters, recorders, and simple laboratory equipment. (RH)

Describes and evaluates a line of modular electronic instruments that are designed for use in physics instruction, including a power supply, function generator, and counter/timer. (MLH)

This article describes the procedures, rationale, and consequences of the steps employed in developing an inhouse instrument to measure achievement in a local career education project. The article attempts to enumerate, clarify, and justify in terms of accepted measurement principles the steps taken in developing an inhouse achievement test.…

Describes a unified experiment in which an optically transparent thin layer electrode is used to illustrate the techniques of thin layer electrochemistry, cyclic voltammetry, controlled potential coulometry, and spectroelectrochemistry. (MLH)

This study designed the Environmental Chemistry Value Preference (ECVP) instrument to assess the value preferences of college non-science majors with respect to certain aspects of environmental chemistry and used the instrument to obtain the value preferences of various groups of non-science majors who had completed some chemistry courses. (BT)

Discusses the increased environmental activities of the National Bureau of Standards which include the development of standard reference materials (each containing a known concentration of a pollutant or pollutants), accurate methods of measurement, and pollution monitoring instruments. (JR)
