This site points students and instructors to web resources which, taken together, allow teaching Instrumental Analysis with a virtual, on-line textbook instead of a hard copy text. Some material is "ASDLib-native," other material is from elsewhere.The website is available here .
This is a module focused on explaining the need for and use of analog-to-digital converters in analytical chemistry. Both a graphical and textual version are available in English and a supplement in Vietnamese is also available.

Lasers are preferred light sources for high resolution or time-resolved optical spectroscopy. This module introduces the workings of lasers and gives examples of common designs.The website is available here .
This site is presented as a guided exploration into the operation of a photomultiplier from the first light incidence to the output signal. Questions guide the exploration and allow (sometimes require)the student to speculate on the result before going forward. A careful, patient student will get a thorough introduction to the operation of a…
The Handbook of Operational Amplifier Application is a complete and exhaustive compendium of Op Amp information. Chapters start with the basic electronics of the internal circuitry of op amps, feedback and analysis of operation followed by ideal and practical op amps. The remaining chapters provide numerous application circuits.The website is available here .
This Quick Time movie illustrates and describes to operation of a Czerny-Turner monochromator. The slits, mirrors, grating and grating scan are described in the production of a specific wavelength at the outlet slit. The movie is a companion to the double beam spectrometer animation.The website is available here .
Basic concepts of signals, noise, and extraction of data from noisy signals are presented as an e-learning module. Excel spreadsheets allow students to vary noise parameters. Basic electronics ideas relating to RC circuits support introductory information on filtersThe website is available here .
This site provides two useful resources for instructors and students of analytical chemistry. The first is a collection of LabVIEW virtual instruments (VIs) for demonstrating topics such as signal-to-noise ratios, boxcar and ensemble averaging, power spectra, digital filtering, analog-to-digital conversions, and the Nyquest frequency. For users that do not have a working copy of LabVIEW, executable…
This site provides a tutorial on electromagnetic waves using animated graphics. The tutorial gives the student the ability to visualize circularly polarized waves, the superposition of various types of polarized waves, and the change that results when the EM waves interact with matter.The website is available here .
This site contains slides to accompany lectures in HPLC. They do not contain enough description for the average student to follow. However, they provide a lot of excellent information about practical aspects of HPLC. The sections on troubleshooting, sample preparation, gradients, system peaks, system suitability and methods validation are particularily valuable. The illustrations and diagrams…
