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)

Described are available electronic laboratory balances. Information was supplied by the manufacturers or importers. (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)

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.

Laser enhanced ionization (LEI) occurs when a tunable dye laser is used to excite a specific atomic population in a flame. Explores the origin of LEI's high sensitivity and identifies possible avenues to higher sensitivity by describing instrument used and experimental procedures and discussing ion formation/detection. (Author/JN)

Discusses developments in electrochemical instrumentation, including the role of computers, measurement/control instruments, present needs and future prospects. Indicates that microprocessors are used primarily for data processing, and that progress depends on noninstrumental factors such as electrode materials. (Author/JN)

Discusses major themes and interrelationships common to bioselective potentiometric membrane electrodes including the nature of bioselective electrodes, applications, and future prospects. Includes tables on traditional ion-selective membrane electrodes, nontraditional electrodes, and typical biocatalytic potentiometric electrodes. (Author/JN)

Presents a description of the world's largest radio/radar antenna, the Areciba Observatory in Puerto Rico. Activities at the observatory are discussed as well as the scientific research in the field of radio astronomy. (SA)

Discusses the role of the Francis Bitter National Magnet Laboratory of the Massachusetts of Technology, and its significance in the world of research. Applications of research on magnetism to medicine are emphasized. (SA)

Reports results of a study for NSF on the scientific instrumentation needs of research universities. Examines current status of scientific instruments in 16 major research universities, six government laboratories, and nine commercial laboratories; and identifies factors that facilitate or impede their acquisition, use, and development. (CS)

Presented are lists of deshielding constants chosen to be easy to remember and to given estimates close enough to measured shifts to allow interpretation of the spectrum of a compound of known structure. (BT)
