We report the design of a low-cost electrochemical workstation and open-source graphical user interface capable of performing a variety of electrochemical methods in an undergraduate teaching laboratory. The instrument--based on the popular Arduino microcontroller board--can be constructed from common components for $40 USD. The modular design of…

This paper outlines a comprehensive teaching laboratory course program that centers on titration analysis, a timeless and essential technique in analytical chemistry spanning various disciplines, such as environmental science, medicine, and industry. In these fields, titration analysis is paramount for determining the concentrations of substances…

This bulletin of Scottish Schools Science Equipment Research Centre provides information about new scientific equipment for use in classrooms and laboratories. The sciences covered are biology, chemistry, and physics. The pieces of equipment can either be purchased from manufacturers or constructed in schools. All descriptions include advantages…

Detailed instructions for the construction of apparatus to detect qualitatively the production of carbon dioxide by respiring organisms are given, with notes on its use and comments on its advantages compared with traditional equipment. The chemistry section of the bulletin contains the results of tests of the efficiency of several laboratory…

Discusses the nature of Fourier transform mass spectrometry and its unique combination of high mass resolution, high upper mass limit, and multichannel advantage. Examines its operation, capabilities and limitations, applications (ion storage, ion manipulation, ion chemistry), and future applications and developments. (JN)

Reviews applications of laser methods to analytical problems, selecting examples from multiphoton ionization and fluorescence analysis. Indicates that laser methodologies promise to improve dramatically the detection of trace substances embedded in "real" matrices, giving the analyst a most powerful means for determining the composition of…

Describes a means of collecting evolved gases which overcomes the usual disadvantages experienced in covering the electrodes with test tubes full of electrolyte solution. (GS)

The design and use of an inexpensive thermistor thermometer is described. In addition to providing a rugged thermometer, using the instruments offers an opportunity to have students become familiar with new principles and techniques, such as principles of thermistors, the Wheatstone bridge, and the concept of calibration.
