Everyone analysing LPG (Liquefied Petroleum Gas) or LNG (Liquefied Natural Gas) knows challenges created by sampling of these products.
To help analysts AlyTech, Francedesigned AURA - LPG/LNG sampling device that safely vaporises the LPG sample into 100% gas phase and deliver to an analyser via heated transfer lines to prevent any condensation. The system is equipped with a heat regulator to set optimal evaporation temperature and build-in pressure regulator keeps the output pressure at a desired value.
The AURA is compliant with ASTM D6667 method “Total Volatile Sulfur in Gaseous Hydrocarbons and Liquefied Petroleum Gases by UVF” and often used for calibration and sample introduction into elemental analysers. All tubing is treated inert to the reactive sulfur compounds and suitable for trace analysis.
In combination with automated gas blender/diluter GasMix™ from AlyTech, the system prepares multi-point calibration standards in LPG matrix. Equipped with an injection valve and flexible software, the GasMix™ system can interface with the analyzer and run fully automatic sequences of routine quality assurance program. Use a LPG standard avoids matrix effects (that may occur if an analyser is calibrated with gases while samples being LPG), giving more accurate results. The solution enables calibration of your analyzer and checks the linearity of response without really limitation on the number of points.
There are many other applications where the AURA helps safely measure LPG samples without the need of sample pressurization, for example injection in GC or GC/MS.
The solution offered by AlyTech significantly increases productivity, providing a maximum operator safety and improve your quality assurance while running LPG samples.
