Safe and easy connection of various sample cylinders.Flexible design allows various configuration options.Representative injection of liquid and/or gaseous hydrocarbon streams.Key Benefits of the DVLS Pressure Station The LPG specification standard D1835 lists the LGI method ASTM D7756 for the residue analysis. The Liquefied Gas Injector method has been standardized in ASTM D7756 and EN 16423 for the analysis of oily residues in liquefied petroleum gases by gas chromatography. This technology has been proven in several applications that require a representative sample injection, such as:įigure Two displays the DVLS Pressure Station combined with the DVLS Liquefied Gas Injector: a dedicated GC solution for high pressure liquid sampling and analysis of C3 - C4 streams such as LPG. The use of high pressure Nitrogen enables the DVLS Pressure Station to control the outlet pressure and flow. Various brands of quick connectors such as Swagelok, Walther and Staubli to install different cylinder sizes on the front side of the station.A configuration for the injection of liquid & pressurized gas samples.A station configured for the injection of pressurized gases.A configuration dedicated to the injection of liquid hydrocarbon samples.Select from the following configuration options to fully meet your requirements: The design of the DVLS Pressure Station offers you a high flexibility as displayed in Figure One. The DVLS Pressure Station keeps the LPG sample in a liquid phase under constant pressure during the injection by using high pressure Nitrogen. Next to resolving the safety concerns, the pressure station keeps the pressure at a constant level to ensure repeatable sample analysis of LPG or other chemicals that are gaseous at ambient pressures. The waste of the sample is vented to a central laboratory waste system. This station handles pressurized gas liquids or gaseous hydrocarbon samples during the injection into a Gas Chromatograph. To allow a safe handling of an LPG sample Da Vinci Laboratory Solutions developed the DVLS Pressure Station.
