Typical Chromatogram
Key Features and Benefits
- The trace sulfur analysis is performed at the same time as the other analyses
- The backflush peak can be tailored to specific samples (e.g. C6+ or C8+ backflush composite peaks)
- Fused silica lined system eliminates trace sulfur reactions during injection
