About this manual

The document details a method for fast hydrocarbon and sulfur simulated distillation (SimDis) utilizing the Agilent Low Thermal Mass (LTM) column technology. This system uses resistive heating to allow rapid temperature programming and extremely fast column cooldown, significantly shortening analytical cycle times compared to conventional air bath GC ovens. The method combines hydrocarbon SimDis with an FID and sulfur SimDis using the Agilent 355 sulfur chemiluminescence detector (SCD) in a series configuration.
