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)

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

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

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…

Describes some undergraduate laboratory experiments on thermoanalytical techniques which deal with both organic and inorganic compounds. (GA)

Explains some experiments involving thermal methods of analysis for undergraduate chemistry laboratories. Some experiments are: (1) the determination of the density and degree of crystallinity of a polymer; and (2) the determination of the specific heat of a nonvolatile compound. (HM)
