Key Features and Benefits
- On-board vaporizer converts liquid to gas phase prior to injection for more repeatable analysis.
- Internally purged diaphragm valves ensure no air contamination and the lowest detection limits possible.
- Ultra-high purity fittings and regulators.
- Specially passivated tubing ensures repeatability and the lowest detection limits.
- Multiple valve cuts used to remove analytes of interest from the matrix.
