Schwarz, Gunnar; Burger, Marcel; Guex, Kevin; Gundlach-Graham, Alexander; Ka¨ser, Debora; Koch, Joachim; Velicsanyi, Peter; Wu, Chung-Che; Gu¨nther, Detlef; Hattendorf, Bodo – Journal of Chemical Education, 2016
A public demonstration of laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) for fast and sensitive qualitative elemental analysis of solid everyday objects is described. This demonstration served as a showcase model for modern instrumentation (and for elemental analysis, in particular) to the public. Several steps were made to…

Jensen, Mark B. – Journal of Chemical Education, 2015
An instrumentation-based laboratory curriculum combining traditional unknown analyses with student-designed projects has been developed for an introductory analytical chemistry course. In the first half of the course, students develop laboratory skills and instrumental proficiency by rotating through six different instruments performing…

Mott, Jenna R.; Munson, Paul J.; Kreuter, Rodney A.; Chohan, Balwant S.; Sykes, Danny G. – Journal of Chemical Education, 2014
The teaching of instrumental analysis for many small colleges and high schools continues to be stymied by high-cost, complicated maintenance, high power requirements, and often the sheer bulk of the instrumentation. Such issues have led us to develop inexpensive instruments as part of a SMILE initiative (small, mobile instruments for laboratory…

Butterfield, Anthony E.; Young, Colin C. – Chemical Engineering Education, 2012
We present a simple, effective, and inexpensive spectrophotometer design that may be used in a stand-alone teaching module, and to enhance various unit operations experiments. The spectrophotometers described performed as well as a commercial option at estimating cell concentration in a bioreactor and tracking a first-order reaction. Such devices…

Farr, John E.; van den Berg, Willem H. – 1982
Microcomputers are commonly interfaced to external devices in scientific, industrial, and consumer settings for data acquisition and for control. The general problem under consideration is the task of taking measurements of some continuous phenomenon, transforming them into digital form, and storing the data in the microcomputer for later use.…

Mak, S. Y.; Young, K. – Physics Education, 1986
Describes a simple method for determining self-inductance of non-ferromagnetic rings. Suggests fitting the ring with an auxiliary coil and using a solenoid driven with a known frequency alternating current. Amplitude change and phase shift can be measured and used to calculate inductance. Material list, calculations, and sample results are given.…
