Abstract: 

Scaling down GC-MS columns and conditions can result in faster semivolatiles analysis times and increased sample throughput, but only when done correctly. In this technical article we demonstrate how to scale an existing method on a traditional format (30 m, 0.25 mm ID, 0.25 µm df) arylene-type column down to a 20 m long, 0.15 mm ID, 0.15 µm df column. By using a properly scaled column and method along with a GC Accelerator oven insert kit, the same separation was achieved with a saving of six minutes per injection.
