Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)

Discussed is an analytical technique that uses photons from lasers to resonantly excite an electron from some initial state of a gaseous atom through various excited states of the atom or molecule. Described are the apparatus, some analytical applications, and the precision and accuracy of the technique. Lists 26 references. (CW)

Presented are system concepts with examples of various vendor approaches for implementing laboratory local area networks. (CW)

This package consists of course syllabi, an instructor's handbook, and a student laboratory manual for a 2-year vocational training program to prepare students for entry-level employment as instrumentation and control technicians. The program was developed through a modification of the DACUM (Developing a Curriculum) technique. The course syllabi…

The skills, understandings, and attitudes necessary for an effective instructional supervisor were identified in the literature (using, for the most part, those materials written since 1975). Twenty-six elements were identified and clustered into six areas for a self-evaluation instrument that can give supervisors a means to describe and analyze…

A questionnaire was mailed to 50 major chemistry departments, 112 smaller chemistry departments, and 25 chemical engineering (CE) departments. The survey (included in an appendix) consists of a series of questions on two broad subjects--the current inventory at the surveyed institutions and the needs for instrumentation. Responses were received…

Discusses some of the new physical dating methods being used by archaeologists and paleoanthropologists to study the material remains of ancient primates. Describes the quaternary physical dating techniques, advances in radiocarbon dating, and the radiocalcium data method. (TW)

Discusses the use of an external analog-digital converter to use a computer as a storage oscilloscope. Provides program listings for use as a unipolar or bipolar voltmeter and storage oscilloscope. Schematics and component list are included. (JM)

Offers suggestions and strategies related to integrating an instrumental approach in high school chemistry. Indicates that the problem-solving process is often clarified using the approach, that the approach improves the quality of the laboratory program, and that it is an effective technique for arousing student interest. (JN)

Describes an experiment suitable for an instrumental analysis or quantitative analysis course. (BB)

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 course which used a student project approach and was designed to replace traditional instrumental analysis. Presents the criteria used for project selection and gives examples of student projects in 1974. (GS)

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)
