Signal-To Noise/Signal Processing

  1. "An Introduction to Signal Processing in Chemical Analysis"
    T.C. O'Haver's online presentation, including figures and links to the special software he used at the U. of Maryland to present this material.

  2. Ok, What's a Strip Chart Recorder?
    Take a trip to the HP Virtual Museum and see . . .

  3. No . . . really . . . What's a Strip Chart Recorder?
    Here's a more modern one that is useful analytically!

Chromatography

  1. "Gas Chromatography" - a QuickTime movie
    T.G. Chasteen's animated simulation of how a GC works; demonstrates split and splitless injection onto a WCOT column with FID detection.

  2. "The Flame Ionization Detector (FID)" - a QuickTime movie
    T.G. Chasteen's animated simulation of how an FID works with a GC.

  3. "Analytical Separations - an online reference"
    Brian Tissue's online compendium of analytical separations methods. Easy to pick out an area to review.

Optical Spectroscopy

  1. Single-Slit Diffraction Simulator
    Simulate the single-slit diffraction process with this online, interactive calculator!

  2. "How a diffraction grating works" - a QuickTime movie
    T.G. Chasteen's animated presentation of how a diffraction grating separates polychromatic light into its characteristic wavelength components.

  3. "How a scanning monochromator works" - a QuickTime movie
    T.G. Chasteen's animated presentation of how a tunable monochromator works.

  4. "How a double-beam absorbance spectrophotometer works" - a QuickTime movie
    Another T.G. Chasteen animation.

  5. "How a photomultiplier tube (PMT) works" - a QuickTime movie
    Yet another T.G. Chasteen animation!

  6. "Analytical Spectroscopy - an online tutorial"
    Brian Tissue's excellent presentation of the essentials of analytical optical spectroscopy (both molecular and atomic). It's even got some online self-test questions to check your comprehension.

  7. "Analytical Spectroscopy - an online reference"
    Brian Tissue's online reference to analytical optical spectroscopy - not as tutuorial-oriented, but allows quick access to selected areas of interest.

  8. "Optical Instrumentation - an online reference"
    Brian Tissue's online compendium of information on optical components in analytical spectroscopic instrumentation.

  9. "The Society for Applied Spectroscopy"
    Homepage for the premier professional organization for optical spectroscopists (publisher of the journal Applied Spectroscopy)

  10. "The Newsletter of the SAS Online"
    The SAS newsletter is a neat resource with a number of fascinating historical articles written by the folks involved in the development and application of new spectroscopic instrumentation (FT-IR, for example). See the section on "History and Reminiscences" for more!

Raman Spectroscopy

  1. The Virtual Raman Spectrometer
    See a real laser Raman spectrometer (NIR excitation with a CCD multichannel detector) - interactive, you can turn on the laser, turn off the room lights and baske in the glow of the first Raman spectrometer used as a detection system for capillary electrophoresis.

Mass Spectrometry

  1. The Virtual Mass Spectrometry Lab
    Can't afford a big Mass Spec lab, but want to experience the thrill of electrospray ionization - ion trap mass spectrometric analysis? Check this out: four mass spectrometers with case studies that walk you through everything from sample prep to spectral analysis. You can almost taste those ions . . .

NMR Spectroscopy

  1. The Basics of NMR
    This is an online, hypertext book that goes through all of the fundamentals of NMR - VERY highly recommended!

  2. NMR Spectroscopy
    This is a reference page (courtesy of Edinburgh University, of web-based NMR resources. There are links to tutorials and online references that deal with the fundamentals of NMR as well as interpretive NMR.

  3. Listen to your NMR
    Ever wonder what that FID sounds like? Wonder no more - take a look here at how you can employ your very own brain to do Fourier transforms on FIDs. Impress your friends and family! Win valuable prizes!
