Typical Chromatogram

Key Features and Benefits

• Can be configured with an additional GC by heated umbilical for simultaneous analysis of hydrogen sulfide, carbonyl sulfide, ammonia cyanide, and hydrogen cyanide.
• Cryogenic cooling may be used to separate argon and oxygen.
• The backflush peak can be tailored to specific samples (e.g. C₆+ or C₈+ backflush composite peaks).
• Separate sampling loops eliminate cross contamination.
• Can be configured with an injector oven for on-line analysis.
• Fast analysis with hydrocarbon analysis through 1,3-butadiene is complete in under 10 minutes.
• Detailed analysis with hydrocarbon analysis through n-eicosane is complete in approximately 30 minutes.
