The DVLS Pressure Station allows a representative sample injection of a liquid or gaseous hydrocarbon stream. The pressure station injects the sample into a GC system and keeps the pressure at a constant level. The Pressure Station is included in the DVLS Liquefied Gas Injector.
For a representative analysis, the sample must remain in the liquid phase during the injection process, this is especially required for LPG or other chemicals that are gaseous at ambient pressures. The DVLS Pressure Station keeps the sample under pressure by adding high pressure Nitrogen to the sample cylinder and controlling the outlet pressure and flow.
The sample container is installed on the front side of the pressure station using the quick connectors. The station keeps the pressure at a constant level. The waste sample is vented to a central waste system or to a waste line that leads the vapor directly outside the building to ensure the lab safety.
The Pressure Station adds high pressure Nitrogen to the sample cylinder and controls the outlet pressure & flow. This technology has been proven in several applications that require a representative sample injection, such as:
The design of the DVLS Pressure Station offers you a high flexibility. Select from the following configuration options to fully meet your requirements:
DVLS Liquefied Gas Injector is a GC solution that has been standardized as ASTM D7756 and EN 16423 for the analysis of residues in liquefied petroleum gases by gas chromatography. Adapting the hardware setup allows to extend the LPG analysis to a wider application range
