The Essential Guide from LCGC’s CHROMacademy presents the third in our series of webcasts on Practical GC Troubleshooting. In this session, 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. We consider the common problems and highlight causes and remedial actions in a very practically relevant way. A must see for everyone working with GC instruments.
