Description:
Shannon Coleman, GC Application Scientist from Agilent presents options that address current helium shortages.
Video Presentation:
This video, part of the knowbeetutoring collection available from Wordpress.com offers a basic but effective introduction to ion production of organic molecules in an electron ionization spectrometer. The basis for fragmentation is explained for the propane molecule using very clear graphics. It is an excellent first exposure to the technique, and supplies a very solid…
This site offers an introductory course (as a MOOC) on the estimation of measurement uncertainty specifically related to chemical analysis (analytical chemistry). The course gives the main concepts and mathematical apparatus of measurement uncertainty estimation and introduces two principal approaches to measurement uncertainty estimation – the ISO GUM modeling approach (aa “bottom-up” approach) and the single-lab…
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 .
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…
This video on YouTube covers the basic principles of infrared spectroscopy. Very useful for a newcomer to IR. This video of 6.5 minute would be useful in a classroom setting or students interested in the technique.
The website is available here .
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…
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…
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…
This site has a video lecture on Scanning Probe Microscopy (SPM) by Prof. R. Reifenberger, Purdue University Nanotech Center. The lecture (accompanied by power point slides) discusses the fundamentals followed by the technical barriers and implementations of surface analysis at atomic dimensions. The context of the material is organized more for a graduate student level, but…
