Complying Accurate and Rapid with ASTM D 6667

Liquefied pressurised gases are valuable feed materials in petrochemical and polymer industry for the synthesis of higher-molecular compounds. But sulphur impurities have negative effects on final products and catalysts. This necessitates a precise monitoring regarding ASTM D 6667. Their pressure requires a special metering technique, which ensures safe sample handling, reproducible dosing, soot-free combustion, and thereby reliable results.

multi EA® 5000 from Analytik Jena (Germany) is the solution. A special dosing valve featuring a Peltier cooling prevents premature expansion of the sample and incomplete combustion. The system can even handle lowest pressures without auxiliary gas. A further advantage is the clearly reduced maintenance effort and the faster analysis due to a flexible selection of the sample volumes.

Fast, accurate readings are now standard in routine labs – independent of operator, sample pressure and element content.
