Describes a low-cost four-color LED photometer developed to overcome the rising cost of laboratory equipment used in general chemistry labs and introduce instrumentation at the undergraduate level. The photometer detects absorbance at selected wavelengths of visible light but retains the advantages of a dual-beam system. The unit is compact and…

For several decades there has been a general concern that the level of research funding for academic instrumentation was not sufficient to keep pace with the requirements of cutting edge research. To develop the factual trend data necessary to understand the depth of the problems in academia and thus provide an adequate response to these concerns,…

Isomeric ketones containing six or seven carbons are separated, illustrating the capability of chemical instrumentation for separating a group of closely related compounds. (MLH)

An operational instrument was designed to approach the tasks of curricular planning and design of university programs in communication in Mexico, or elsewhere in the Third World. The instrument was designed by the Mexican team of advisors at the Workshop-Seminar on Curriculum Planning, held in Villa de Leyva, Colombia, in May of 1987. It was used…

Describes the structure and content of the laboratory course sequence of the Engineering College of the State University of New York at Stony Brook. The multidisciplinary laboratory sequence is a core requisite take n in the junior year, and instructs students in experimental methodology, including measurement and instrumentation theory. (JR)

Identifies a trend in analytical chemistry toward greater use of instruments and a need for an understanding of the basic principles involved in instrumentation. This need can be fulfilled using homebuilt equipment; examples are provided in the areas of electrolytic conductance and electronic coulometry. (GS)

Several teaching aids including a microcomputer system, a process control laboratory, a mechanics laboratory, and a teaching polariscope are described. (RH)

An instrument to assess specific attitudes toward humanistic teaching strategies as well as toward science teaching was designed. (Author/GA)

Discussion is focused on one phase of the assessment problem--the development and improvement of instruments that can be used to measure the observable performance of competence of preservice teacher education students. (Author)

Explores questions, dilemmas, and issues facing individuals who teach and/or development undergraduate curricula in chemical instrumentation. Areas addressed include the instrumental analysis course, the laboratory, the role of electronics, and computer use. (JN)

Describes an experiment for recording two individual spectrophotometer response curves. The two curves are directly related to the power of transmitted beams that pass through a solvent and solution. An absorption spectrum of the solution can be constructed from the calculated rations of the curves as a function of wavelength. (JN)

Highlights an American Chemical Society (ACS) survey of 103 chemistry departments on their instrumentation needs. The 2-year study affirms that instruments used for chemical research and education are becoming outdated because of their age and changes in technology. The survey also reveals how departments plan to use newly acquired instruments.…

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)
