Presents two lists: (1) important considerations for any total chemical analysis and (2) a condensed version that can be used by students to evaluate each analytical procedure. Benefits of using the condensed version (such as seeing that instrumentation is only one of several components of an analysis) are noted. (JN)

Examines trends in methods for deriving chemical information from a variety of systems and environments, focusing on improvements in sensitivity, specificity, speed and simplicity, and in sampling. Indicates that the increasing importance of analytical instrumentation requires reexamination of its coverage in educational curricula. (JN)

The basic principles, current techniques, instrumentation, and possible chemical applications of nuclear magnetic resonance (NMR) imaging are discussed. (JN)

This course is designed for those requiring an introduction to instruments commonly used in water pollution analyses. Examples are: pH, conductivity, dissolved oxygen meters, spectrophotometers, turbidimeters, carbon analyzer, and gas chromatographs. Students should have a basic knowledge of analytical chemistry. (CO)

Describes an experiment for recording two individual spectrophotometer response curves. The two curves are directly related to the power of transmitted beams that pass through a solvent and solution. An absorption spectrum of the solution can be constructed from the calculated rations of the curves as a function of wavelength. (JN)

Laser enhanced ionization (LEI) occurs when a tunable dye laser is used to excite a specific atomic population in a flame. Explores the origin of LEI's high sensitivity and identifies possible avenues to higher sensitivity by describing instrument used and experimental procedures and discussing ion formation/detection. (Author/JN)

Presented are lists of deshielding constants chosen to be easy to remember and to given estimates close enough to measured shifts to allow interpretation of the spectrum of a compound of known structure. (BT)

Some of the important modern developments of thin-layer chromatography are introduced. Discussed are the theory and instrumentation of thin-layer chromatography including multidimensional and multimodal techniques. Lists 53 references. (CW)

Describes a combined demonstration and student experiment course to illustrate fundamental techniques, instrumentation, and concise report writing. Describes experiments including tensile tests, heat treatment, equilibrium diagram, microexamination, strain measurement, and recrystallization. (GH)

Presents three ideas to help hold costs down in purchasing and using science equipment. These include (1) use of pencils and other graphite rods as sensors in potentiometric titrations, (2) rubber bulb modification for pipetting, and (3) a heater for a glassware bath. (JM)

Discusses the theory and experimental procedures for using Young's eriometer to determine the diameters of blood corpuscles, lycopodium powder, and wool fibers. (CC)

Major instrumental concerns in molecular solution fluorimetry have recently turned away from sensitivity enhancement to an orientation more directed toward selectivity. This trend simply recognizes that such methodology has historically been blank limited. Thus, the described uses of liquid chromatography, line narrowing, and time resolution…

Describes modification of a gas viscometer to produce a low cost instrument with high precision and safe design. Three tungsten electrodes are mounted in the viscometer using graded glass seals and a ball trap is inserted between mercury reservoir and all external stopcocks. Also describes modifications in experimental procedures. (Author/JN)
