Strategies for Helium Carrier Gas Conservation and Transition to Alternative Carrier Gas

Description: Shannon Coleman, GC Application Scientist from Agilent presents options that address current helium shortages. Strategies for Helium Carrier Gas Conservation and Transition to Alternative Carrier Gas This discussion will focus on understanding tactics for carrier gas conservation, including what hardware and strategies are available for conservation.  Alternative carrier gas options will be explored, as…

Introduction to Mass Spectrometry Video

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…

ESTIMATION OF MEASUREMENT UNCERTAINTY IN CHEMICAL ANALYSIS

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…

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…
