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…

Discusses working implementations of artificial intelligence systems for chemical laboratory applications. They include expert systems for liquid chromatography, spectral analysis, instrument control of a totally computerized triple-quadrupole mass spectrometer, and the determination of the mineral constituents of a rock sample given the powder…

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 a microcomputer-based laboratory (MBL) study (n=75) which uses multiple temperature gathering devices (mercury thermometer, digital thermometer, and computer probe) and graphing methods (hand graphs, delayed computer graphs, and real-time graphs). Reports that MBL real-time graphing provides significant increases in graphing skills. (MVL)

This report describes a Prescription Learning Company basic mathematics multi-media laboratory at an elementary school in Austin, Texas. Research assumptions that the Prescription Learning approach makes are explored and reviewed. A sample of 12 fifth grade students participated in attitude and achievement results of the laboratory. Twenty-four…
