RSC.org: Mass Spectrometry

This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of mass spectrometry, using a magnetic sector instrument to demonstrate how specific m/z ratios can be selected. The theory and operation of MS, including the chemistry of ionization and fragmentation is described at an introductory level. There's also an excellent…

HPLC

This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of HPLC. This video is a short primer (~5 min) which introduces the basic technique and instrumentation. The theory of HPLC is described at a very basic level. Separation theory is presented in a qualitiative fashion, and both the mechanics…

Introduction to Atomic Force Microscopy (AFM) Video Lecture

This site has a video lecture on Atomic Force Microscopy (AFM) by Prof. Arvind Raman of Purdue University that discusses the development, instrumentation, and operational principles of various AFM imaging 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. It…

Micromechnical Biosensors and their Integration with Aptamer-based Receptor Molecules

This site is one of many on \\\"nanoHUB.org\\\" which highlights availability of on-line simulations. This particular one provides a video of a research seminar on the topic of micromechanical biosensors focusing on aptamer-based receptor molecules. The quality of the graphics in the video is not high - mainly, the smallness of the visuals makes it difficult…

Basic Microscopy Concepts

The site provides introductory information related to optical microscopy. Among the topics addressed are resolution, numerical aperture, depth of field, field of view, illumination and the useful magnification range. A section on fluorescence microscopy is also included. Interactive video is used to demonstrate concepts in some cases. Researchers and educators interested in a brief overview of…
