Complying Sulfur in LPG Accurate, Rapid and Safe with ASTM D 6667 – multi EA® 5000

Liquefied pressurized gases are valuable feed materials in petrochemical and polymer industry for the synthesis of higher-molecular compounds.

But sulfur impurities have negative effects on final products and catalysts. This necessitates a precise monitoring regarding ASTM D 6667 and ASTM D 7551. Their pressure requires a special metering technique, which ensures safe sample handling, reproducible dosing, soot-free combustion, and thereby reliable results.

multi EA^® 5000 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.
