Quantitative Analysis of Nail Polish Remover Using Nuclear Magnetic Resonance Spectroscopy Revisited  Markus M. Hoffmann, Joshua T. Caccamis, Mark P. Heitz, and Kenneth D. Schlecht
Substantial modifications intended for a second- or third-year laboratory course in analytical chemistry are presented for a previously described procedure using NMR spectroscopy to quantitatively determine analytes in commercial nail polish remover. The revised experiment introduces student collaboration to critically interpret a relatively large set of data.

Digitally Enhanced Thin-Layer Chromatography: An Inexpensive, New Technique for Qualitative and Quantitative Analysis  Amber Victoria Irish Hess
Thin-layer chromatography enhanced by digital photography is ideal for high school and college labs and can perform qualitative and quantitative analysis comparable to more expensive, high-performance TLC equipment. Using common photo-editing software, one can quickly produce multi-spectral scans, densitograms, and calibration curves, output previously limited to HPTLC.

The construction of a simple, low-cost, stand-alone lock-in amplifier suitable for physical and analytical chemistry instructional laboratories is described. The instrument is useful for detecting and amplifying signals that are in-phase with a reference signal and is particularly important for optical experiments that employ a pulsed light source.

Automatic Low-Cost Data Acquisition from Old Polarimetric Instruments  Giuseppe Alibrandi, Santi D'Aliberti, Salvatore Coppolino, Antonino Villari, and Norberto Micali
This article describes the design of an apparatus that allows the digital acquisition of polarimetric data from a Lippich polarimeter. This apparatus consists of a low-cost telecamera applied to the ocular of a double-field polarimeter and connected to a PC. The camera is able to reveal with high sensibility the difference in brightness in the two fields allowing more accurate analytical data to be obtained, without need for the analyser to be rotated. This apparatus allows the execution of either single observations or kinetics, because it is able to save previously obtained analytical data.

The History of Ion Chromatography: The Engineering Perspective  Barton Evans
This article traces the history of the engineering development related to the several generations of ion chromatography instruments, columns, suppressers, and software. In so doing, several representative engineering challenges and their outcomes are discussed including: early directions (traveling without a road map, or "going where the applications are"), dealing with an extremely corrosive mobile phase (aka: the "eluent"), resolving the inherent incompatibilities of nonmetallic flow paths with the benefits of high-pressure, elevated temperature operation, managing the ever-evolving nature of the suppressor, coping with requirements for ultra high-end online systems, and providing extremely simple-to-use dedicated analyzer systems.

Ion Chromatography: An Account of Its Conception and Early Development  Hamish Small
In the late 1950s, a small group of chemists at the Dow Chemical Company envisioned replacing these classical methods of inorganic analysis with but a single, universal chromatographic technique. They called their project "Inorganic Chromatography". This article describes how they developed this concept into a new technique, ready for commercial development into what we know today as "Ion Chromatography". In particular, the account will describe: how the Dow scientists adapted electrical conductance monitoring to chromatography, the introduction of the suppressor to chromatography, the invention of special stationary phases, and the evolution of strategies and principles that would shape and guide the practice of ion chromatography for many years to come.
