Discusses the nature of Fourier transform mass spectrometry and its unique combination of high mass resolution, high upper mass limit, and multichannel advantage. Examines its operation, capabilities and limitations, applications (ion storage, ion manipulation, ion chemistry), and future applications and developments. (JN)

Reviews applications of laser methods to analytical problems, selecting examples from multiphoton ionization and fluorescence analysis. Indicates that laser methodologies promise to improve dramatically the detection of trace substances embedded in "real" matrices, giving the analyst a most powerful means for determining the composition of…

Describes a new, modified "flash chromatography" apparatus which overcomes difficulties found in conventional apparatus. For example, an expensive teflon pressure valve is not necessary in the modified version. The apparatus is suitable as an instructional tool in undergraduate courses. (JN)

Provides additional recommendations as the Health and Safety at Work Act of 1974 applies to the storage of flammable liquids, provision of safety equipment, responsibility for technicians and faulty apparatus. (GS)

Discusses what can occur in a laboratory if a cylinder valve is separated from a compressed gas cylinder. (MLH)

Gives brief descriptions of new physics laboratory equipment and available literature describing laboratory equipment. (MLH)

Describes commercially available permanent magnets that have been incorporated in a compact and inexpensive structure providing both field sweep and modulation suitable for electron spin resonance at microwave frequencies. (MLH)

Describes oscillograph-type laboratory recorders and accessory equipment such as paper drives, printing mechanisms, amplifiers, and integrators. (MLH)

Discusses how sophisticated instrumentation techniques yield practical results in three typical materials problems: fracture analysis, joining, and compatibility. Describes techniques such as scanning and transmission electron microscopy, and Auger spectroscopy. (MLH)

This entire issue is devoted to a listing of available laboratory instruments and equipment. Names of instruments appear in alphabetical order; names of manufacturers of each instrument appear under each instrument entry, and a separate section lists manufacturers' addresses. (MLH)

This booklet presents some activities to measure various weather phenomena. Directions for constructing a weather station are included. Instruments including rain gauges, thermometers, wind vanes, wind speed devices, humidity devices, barometers, atmospheric observations, a dustfall jar, sticky-tape can, detection of gases in the air, and pH of…
