The Encon Evolution was designed from the beginning with the user in mind. The system needed to provide high productivity, stability, reliability and fast maintenance to meet the needs of today’s laboratory.
The Encon Evolution is designed to remove water during the purge process. EPA methods require you to purge between 40-50ml/min of flow. As you purge, the water and VOCs travel through a Moisture Reduction Trap (MoRT) on the way to the analytical trap. This prevents a large amount of moisture from contacing the analytical trap. By using an 8-port valve instead of a 6-port valve, the sample during desorption goes directly to the GC. In other systems the sample flows through a moisture system during this step. This creates a lot of extra volume in the desorption pathway, allowing peaks to broaden, sacrificing peak resolution.
