GC-MS Ionization Processes l Live Webcast & Tutorial

Thursday 24th April 2014, 16:00 GMT

GC-MS Ionization Processes The focus of this month’s Essential Guide webcast is GC-MS ionization processes. The two main forms of ionization, Electron Ionization (EI) and Chemical Ionization (CI), will be discussed in depth. The molecular reactions which occur within the ion source to produce ions will be examined along with which form of ionization should be used for particular analytes. Finally, our speakers Dr. John Langley (Southampton University) and Tony Taylor (Crawford Scientific) will impart some of their expert knowledge regarding optimization of the GC-MS process and some general interpretation strategies.

Critical Choices in HPLC – Selecting Column Stationary Phase and Dimensions l On Demand Webcast & Tutorial

Thursday 20th March 2014, 8:00AM PDT/ 11:00AM EDT/ 15:00 GMT/ 16:00 CET

HPLC Selecting Column Stationary Phase and Dimensions How do you currently select a column for an HPLC application? Do you just use the one that is on the instrument, root around in an old drawer and hope that you pull out one that works, use your favorite C18 or ODS column, or borrow one from a colleague who’s chromatography is currently working particularly well? These are probably not ideal situations but there will be many of us who are guilty of these exact scenarios. Instead, why not join us for the CHROMacademy Essential Guide webcast on HPLC column selection.
