Typical Chromatogram



Key Features and Benefits
- Liquid valves can be added for LPG analysis
- The backflush peak can be tailored to specific samples (e.g. C₆₊ or C₈₊ backflush composite peaks)
- Can be converted to all capillary columns to achieve better resolution and detection limits
- A fourth FID can be added for the simultaneous analysis of trace carbon oxides
