Animating the Split / Splitless Injection Process
Often the most difficult concepts to understand are those which we cannot observe. This would include, for the novice user, the valve processes and flow paths of carrier and sample vapour through a split / splitless injector. CHROMacademy uses explanatory animations to bring these processes to life and for the end user to gain a much deeper understanding of the injection process in GC – including full descriptions of each variable and how these might be optimized to obtain the best sensitivity and sample fidelity.

Troubleshooters
Most folks have a troubleshooting poster on their laboratory wall to help them quickly cross-check symptoms and identify problems with equipment and separations. At CHROMacademy we have taken this concept several steps further. Our interactive troubleshooters allow you to choose combinations of chromatographic and instrument symptoms and use an algorithm built on over one hundred years of combined chromatographic experience to suggest the most likely causes – appropriately ranked. Each cause is described and possible solutions given. Each cause is accompanied by supporting materials drawn from thousands of LCGC, CHROMacademy and Vendor articles and resources.

Translating GC Methods from Helium to Hydrogen Carrier Gas
Live: Thursday October 18 at 4:00 BST; 11:00am EST

As Helium supply issues and prices escalate, many GC users are considering a switch to an alternative carrier gas, usually Hydrogen. This webcast and Essential Guide outlines the critical issues which need to be addressed when considering the use of Hydrogen including:

• Safety aspects of hydrogen use (cylinders and generators)
  
• Ensuring retention time transfer
  
• Guarding against selectivity changes
  
• Method translation software
  
• Using hydrogen with GC-MS instruments
  
• Using hydrogen with 0.53mm i.d. columns
  
• Making use of hydrogen to develop faster separations
  
• Instrument considerations – dead volumes and carrier gas settings
