Using a Diode Laser Pointer to Count Drops and Automate Titration Systems  Paul Ogren, Steve Nelson, and Ian Henry
A diode laser pointer is used to construct a simple system for recording drops falling from a buret. The drop signal is recorded together with one or more measurement signals by a LabVIEW-based programmable interfacing system. A standard buret is converted to a Mariotte buret to provide a constant drop-addition rate.

A Guided Inquiry Approach to NMR Spectroscopy  Laura E. Parmentier, George C. Lisensky, and Brock Spencer
The authors present a novel way to introduce NMR spectroscopy into the general chemistry curriculum as part of a week-long aspirin project in their one-semester introductory course. Purity is determined by titration and IR and NMR spectroscopy.

A General Chemistry Experiment Incorporating Synthesis and Structural Determination  Hal Van Ryswyk
An experiment for the general chemistry laboratory is described wherein gas chromatography-mass spectroscopy (GC-MS) and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) are used to characterize the products of a series of microscale reactions on vanillin.
