Chase, D. L.; And Others – 1972
Total mercury in ambient air can be collected in iodine monochloride, but the subsequent analysis is relatively complex and tedious, and contamination from reagents and containers is a problem. A sliver wool collector, preceded by a catalytic pyrolysis furnace, gives good recovery of mercury and simplifies the analytical step. An instrumental…

Keedy, Curtis R.; Abele, John C. – Journal of Chemical Education, 1985
Describes a two-term course in electronic instrumentation for chemistry and physics students. The first term focuses on analog circuits and the measurement of voltage, current, and impendance. The second-term course focuses on digital pulses/logic, microcomputer organization, and assembly language programing and interfacing to experiments. (JN)

Strobel, Howard A. – Journal of Chemical Education, 1984
Describes a modular approach to help select the most effective instruments for particular applications. In the approach, an instrument is considered to be a system composed of modules, each module performing a particular function. General input/output functions of various modules, how they modify signals, and module sensitivity are discussed. (JM)

Shukla, Shyam S.; Rusling, James F. – Analytical Chemistry, 1984
Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)
