Analyse More Semivolatiles Samples Per Shift Using Split Injection

This technical note from Restek studies the use of split injection for increased sample throughput for semivolatiles analysis. By employing split injection with a higher initial GC oven temperature and faster cycle time, analysis times are fast with improved repeatability allowing more samples to be run per shift. Results indicated that by splitting off a portion of the sample, less column maintenance will be required and that using split injection for semivolatiles analysis offers significant advantages over splitless injection.
