This article discusses how to increase the maximum achievable oven program rate by reducing the GC oven volume to shorten the GC analysis time. Comparisons were made between the Agilent 6890 Plus GC with Oven Insert and the Agilent 6850 Series GC, showing a dramatic increase in oven program rate with the use of the 6890 GC oven insert.
Decreasing gas chromatography (GC) analysis time is critical for increasing sample throughput and reducing operating costs. This document discusses how using a specific oven insert with the Agilent 6890 Plus GC can substantially increase the maximum obtainable oven program rate by reducing the overall oven volume, allowing the column and sample to heat more quickly.
The relative standard deviation is below 0.05 percent for all instruments with and without the insert.
