Main Products Area : Series 4000 SFC : Features : New Secondary Column Oven

New Secondary Column Oven

Independent column heater, especially useful when
two different column temperatures are desired

Optional secondary column heater with independent temperature control.

Custom design for column switching techniques used for petroleum analysis.

The secondary column heater conveniently mounts to the wall of the oven cavity.

ASTM D6550 testing method is improved

The oven cavity is maintained at a lower temperature to optimize the separation of saturates and aromatics, while the silver-loaded silica column can be maintained at up to 200°C to optimize the interactions between the olefinic compounds and the silver ions.

Olefin peak shape is greatly improved and the sensitivity is increased.

Decreased tailing on the olefin peak caused from overly strong olefin interaction with the silver ions, significantly decreases analysis run times.
