Temperature Programmed GC: Why Are All Those Peaks So Sharp?

Temperature programming is used for most separations in capillary GC today. Despite this, many of the principles by which we understand temperature programmed capillary column separations are based on ideas developed using packed columns and isothermal conditions. This instalment of "GC Connections" dives into temperature programming. Read more
