Key Features and Benefits

• Fused silica lined tubing ensures repeatability and the lowest detection limits.
• Sulfur treated inlet and sample lines ensure no sulfur lost during sample introduction.
• A 3-way decoking valve alleviates any coking problems that might occur in the SCD burner during the oxidation process and ensures maximum response and consistency.
• The backflush peak can be tailored to specific samples (e.g. C₆+ or C₈+ backflush composite peaks).
