Isomeric ketones containing six or seven carbons are separated, illustrating the capability of chemical instrumentation for separating a group of closely related compounds. (MLH)

Describes an experiment designed to familiarize students with the operation of a precision spectrophotometer, the effects of changes in operating variables, and the characteristics of such components as sources and detectors. (SLH)

Identifies a trend in analytical chemistry toward greater use of instruments and a need for an understanding of the basic principles involved in instrumentation. This need can be fulfilled using homebuilt equipment; examples are provided in the areas of electrolytic conductance and electronic coulometry. (GS)

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)

Discussed are various types of electronic laboratory balances. (RH)

Described are available electronic laboratory balances. Information was supplied by the manufacturers or importers. (RH)

A variety of materials are described including spectrophotometers, chromatographs, voltmeters, recorders, and simple laboratory equipment. (RH)

Describes a unified experiment in which an optically transparent thin layer electrode is used to illustrate the techniques of thin layer electrochemistry, cyclic voltammetry, controlled potential coulometry, and spectroelectrochemistry. (MLH)
