Lubricant of the global economy Nowadays crude oil, which consists of at least 500 differ- ent components, is processed by distillation and refining to produce liquefied gas, gasoline, diesel, heating fuel, and lubricants as well as a large variety of other products. As the «lubricant» of the global economy, crude...Read More

They can release hydrogen sulfide in acidified water, which is toxic in even minuscule amounts. The  ISE Application Note I-013 "Sulfide in water in accordance with ASTM D4658" describes the determination of sulfide concentration in water via direct measurement with the Ag/S-ISE in accordance with ASTM D4658.Read More

Distillation vs Ion Chromatography Typical analysis of total nitrogen requires a distillation followed by colorimetric determination. As distillation is a tedious process and not reproducible, errors are easily introduced. ASTM D8001 provides a simple solution for simultaneous determination of total nitrogen and phosphorus using the robust Metrosep A Supp 16...Read More

Copper-silver ionization Copper-silver ionization disperses positively charged copper and silver ions into the water system. The ions bond electrostatically with negative sites on bacterial cell walls and denature proteins. Over the long term, the presence of copper and silver ions destroy biofilms and slimes that can harbor Legionella, the bacteria...Read More

Quality control of catalysts with the Camsizer P4 from Retsch Technology The analysis of size and shape plays an important role for the quality control of catalysts. Sieve analysis is often used for this, however, it only provides the required size information for spherical particles. Rods, for example, pass the mesh with a particular orientation which makes...Read More

Nitrogen and Phosphorus The analysis of nutrients in soil and water is very important to farming and environmental health. A lack of nitrogen or phosphorus in soils will inhibit crop growth. An excess can lead to unwanted organic growth in waterways due to runoff waters. ASTM D8001 Historically, total nitrogen...Read More
