DVLS Pressure Station

The DVLS Pressure Station allows a safe and representative sample introduction of (liquefied) gases. The Pressure Station introduces a (liquefied) gas sample into a chromatographic system and keeps the pressure at a constant level. The Pressure Station is included in the DVLS Liquefied Gas Injector.

Safe & Representative Sampling of (Liquefied) Gases

For a representative analysis, the liquiefied gas sample must remain in the liquid phase under constant pressure during the injection process. This is especially required for LPG or other liquefied gases.

The sample cylinder is mounted onto the Pressure Station using quick connectors. For liquefied gas samples the Pressure Station adds high pressure Nitrogen to the sample cylinder, which controls the outlet pressure and flow. The sight glass enables a visual check of the liquid phase of the sample. The sample is introduced as a liquid using an external injection device such as a Liquefied Gas Injector or a Liquid Sampling Valve.
Optionally the Pressure Station can also be configured with a vaporizer to prevent freezing of the sample waste. The waste sample is vented to a central waste
