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.

Abstract: 

Polycyclic aromatic hydrocarbons (PAHs) are analyzed at low levels around the world in order to protect human and environmental health. The PAH GC-MS analysis shown here uses SIM mode and column and method parameters scaled down from a commonly used semivolatiles method. Good chromatographic results were achieved down to 0.05 ng on-column in a fast, 15-minute analysis time.

Abstract: 

Have a reliable method, but need results faster? EZGC method translation software makes it easy to get an equivalent separation in less time. By moving to a shorter column and adopting the translated method conditions, you can significantly reduce your analysis time. Agilent users can further speed up their analyses by installing a GC Accelerator oven insert kit.

Same Separation, Speedier Solution

GC Accelerator Oven Insert Kit Product PhotoDesigned with GC-MS users in mind, the GC Accelerator kit provides a simple way to speed up sample analysis. By reducing oven volume, these inserts allow faster ramp rates to be attained, which reduces oven cycle time and allows for increased sample throughput and more capacity to process rush samples. When faster ramp rates are used, existing methods can be accurately scaled down to smaller, high-efficiency, narrow-bore columns using Restek’s EZGC method translator. With a scaled-down column, a properly translated method, and a GC Accelerator kit, you can obtain the same chromatographic separation—often with greater sensitivity—in a fraction of the time without making a capital investment.
