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).
