Key Features and Benefits

  • Gas chromatograph can be configured to contain additional applications.
  • Fused silica lined tubing ensures repeatability and the lowest detection limits.
  • High selectivity and equimolar for sulfur.
  • 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.
