Illustrates the state of the art in pyrolysis mass spectrometry techniques through applications in: (1) structural determination and quality control of synthetic polymers; (2) quantitative analysis of polymer mixtures; (3) classification and structural characterization of fossil organic matter; and (4) nonsupervised numerical extraction of…

In a modular approach, instruments are considered as systems composed of modules, each module performing a particular function. Examines process of relating specifications for instruments to those for particular modules, effect of microcomputers on modular approach, and extension of the approach to such devices as "hyphenated" or tandem…

A controversy has arisen as to whether instrument vendors are providing sufficient information about instrument-associated software to permit users to understand invisible data transformations going on inside of the equipment. Topics addressed include software protection, user modifications, and publishing software. (Author/JN)

Described is the use of a general purpose hybrid computer in controlling and monitoring certain experiments on human subjects. In these investigations, researchers produce various sensory stimuli and measure participants' responses as voltage produced at a scalp node. The computer system discussed facilitates implementation of these experiments as…

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)

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)

The use of microelectronics and computers in medicine is reviewed, focusing on medical research; medical data collection, storage, retrieval, and manipulation; medical decision making; computed tomography; ultrasonic imaging; role in clinical laboratories; and use as adjuncts for diagnostic tests, monitors of critically-ill patients, and with the…

Describes a two-term course in electronic instrumentation for chemistry and physics students. The first term focuses on analog circuits and the measurement of voltage, current, and impendance. The second-term course focuses on digital pulses/logic, microcomputer organization, and assembly language programing and interfacing to experiments. (JN)

Discusses various topics related to the interfacing of computers, focusing particularly on methods of data collection using instruments. Topics include serial digital connections (examining RS 232C and V.24, physical protocol, electrical protocol, and other areas) and parallel digital connections. (JN)

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)

Describes laboratory workstations which provide direct connection for monitoring and control of analytical instruments such as pH meters, spectrophotometers, temperature, and chromatographic instruments. This is accomplished through analog/digital and digital/analog converters for analog signals and input/output devices for on/off signals.…

Described is a project SIINC (Scientific Instrumentation Information Network and Curriculum), a three year pilot program to test the feasibility of developing a computer-based system for accessing information vital to users of chemical instrumentation. Project SIINC fills the gap between conventional sources of instrumental information and…
