Techniques for detection and measurement of carbon monoxide (CO) in air are of interest and utility in many aspects of automotive safety. CO concentrations may range from less than 100 parts per million (ppm), or 0.01 percent, to about 10 percent by volume. Gas indicator tubes have been used for many years primarily as detectors of hazardous gases…

The sensor is a mass spectrometer system which continuously monitors the atmospheric constituents of hydrogen, water vapor, nitrogen, oxygen, and carbon dioxide, and monitors the Freons on a demand sampling basis. The manual provides a system description, operational procedures, and maintenance and troubleshooting instructions. Circuit diagrams…

Describes surface-finish characteristics and presents an approach by which the teacher may incorporate these new materials into a course of study. (GR)

A study of the development of commercial electron spectroscopy of chemical analysis (ESCA) instrumentation over a span of three decades is presented. The field has also been extended significantly by use of synchrotron radiation as a bright X-ray source, which has opened new areas of research in solid-state physics, molecular biology, and many…

When embedded within a continuum of mental health services including both prevention and treatment, school-based mental health identification programs can promote improved academic and mental health functioning among students. This article describes the scientific status of assessment instrumentation that may be used for early mental health…

Note is presented on the standard lab from a second year chemistry course. The lab "Determining which of the Seven FD&C Food-Approved Dyes are Used in Making Green Skittles", familiarizes students with the operation of the CHEM2000 UV-Vis spectrophorometer.

Describes the desk top calculators now on the market, including manufacturers, prices, and functions performed. Provides a table of specifications for programmable desk calculators. (MLH)

This article discusses an instrument devised to provide objective and reliable information about the fundamentally time-dependent nature of observable motor performance. (Author)

Discussed and described are analytical instruments available for chemical analysis in 1940-41. (RH)
