In this tutorial with accompanies the Essential Guide Webcast (see opposite), Dr. John Hinshaw (Senior Scientist , BPL Global Ltd) and Tony Taylor (Technical Director, Crawford Scientific), present practical troubleshooting tips for GC separations, with special emphasis on retention time variability, loss of efficiency and poor peak shape. The session includes a wealth of practical information on GC separation issues and all our real world problems are related to both separation chemistry and hardware issues. A ‘must read’ for everyone working with GC instruments VIEW ENTIRE TUTORIAL
Key Learning Objectives
•
Learn how to quickly identify separation problems in GC
•
Investigate causes of retention time variability and how to fix and prevent issues with carrier gas flow rate reproducibility and injection acquisition parameters
•
Highlight major causes of peak shape deformation, including peak tailing caused by activity within the system and key preventative measures to minimize secondary retention and maximize sensitivity / peak area reproducibility
•
Investigate the reasons for efficiency loss in GC and develop strategies to prolong column lifetime and maximize system efficiency
•
Develop curative and preventative maintenance operations to optimize GC separation quality
