Animation of pulse dampner in HPLC
This animation site deals specifically with pulse dampners is LC and could help in a general lecture about LC pumps. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) are also listed on ASDL.
Atomic Emission Spectroscopy
A learning module that explains the instrumental systems and interactions involved in atomic emission for elemental analysis. Completion of the module will leave the learner with knowledge of optics, plasma sources, and trade-offs in choosing the right instrument for a given analytical task.
RSC.org: UV/Vis Spectroscopy
This video distributed on YouTube is on the basic principles of UV/Vis. Provides a good primer (~5 min), and the top-off look of the instrument is useful in explaining components. A double beam instrument is described.
RSC.org: Gas Chromatography
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of GC. This video is a short primer (~5 min) which introduces the technique and instrumentation. There are many assumptions that are made in the presentation of this material, due to the fact the video is meant to be a basic introduction. Examples of such assumptions include the statement that volatility solely controls the elution order of volatile compounds on a GC column and that concentration
Atomic Force Microscopy
A video lecture on Atomic Force Microscopy (AFM) by Prof. Arvind Raman of Purdue University that discusses the historical development, instrumentation and operational principles of various AFM modes. The lecture is accompanied by power point slides with clear illustrative graphics. Basics are provided in the application examples with advantages and limitation discussed. Useful site to those interested in learning AFM.
Fluorescence Correlation Spectroscopy
Previously published as part of an online biophysics textbook, the article has rich and fairly complete scientific content.
NMR of Paramagnetic Proteins
This site presents an overview of techniques used for structural elucidation of paramagnetic metalloproteins. The content is directed to the more advanced NMR user and would be suitable for an upper division or graduate level NMR class.
A Pictorial Representation of Product Operator Formalism: Non-Classical Vector Diagrams for Multidim
This site presents a pictorial description of the product operator formalism using a non-classical vector approach. This approach allows for the representation of any arbitrary multidimensional or heteronuclear NMR experiment. A description of a complete set of 16 vector representations for weakly-coupled two-spin (I=1/2) systems is given followed by an extension of this set to three-spin systems. Finally the concepts of coherence transfer, multiple quantum spectroscopy and phase cycling are ill
Busy Researchers Guide to Chromatography
The Busy Researchers\' Guide to Chromatography is a pdf book focused on the vendor\'s (PerSeptive Biosystems) products (perfusion-based chromatography) with an eye toward their application in bioanalysis. The book is a nicely written and practical introduction to chromatography suitable for use with undergraduates. The last several chapters define the basics of liquid chromatographic separations and the first few give a nice overview of how one does a method development for a specific biologic

Bulk Density Protocol
The purpose of this resource is to measure the bulk density of each horizon in a soil profile. In the field, students collect three soil samples from each horizon in a soil profile using a container with a measured volume. In the classroom, students weigh the samples, dry them, and weigh them again to determine their dry mass and water content. Students then sieve the dry soil samples and measure the mass and volume of any rocks and material with dimensions greater than 2 mm. Students use the Bu

Who Invented Geometry?
A brief video explaining that geometry was invented or formalized by the ancient Greeks about 4,000 years ago. A math teacher explains who invented geometry using a whiteboard as a visual in the video. The narrators speech is shown as text on the bottom of the screen.
Students learn about the physical force of linear momentum movement in a straight line by investigating collisions. They learn an equation that engineers use to describe momentum. Students also investigate the psychological phenomenon of momentum; they see how the "big mo" of the bandwagon effect contributes to the development of fads and manias, and how modern technology and mass media accelerate and intensify the effect.
