Beryllium Laboratory Analysis The Synergist
Tables 1 and 2 show the relationships between beryllium air sampling rates, amount of volume collected, and the resulting lab detection limit. ISO 20581 and best practices set the detection limit for the analytical laboratory at 10 percent of the OEL. This means that if the target OEL is the ACGIH TLV of 0.05 µg, the lab should have an LOD of 0.005 µg (5 ng). According to the

Beryllium NIOSH CDC
Beryllium is a naturally occurring metal found in several minerals. It is most commonly extracted from beryl and bertrandite ores. Beryllium and beryllium-containing alloys and compounds have been produced commercially in the US since the 1940s. Production of beryllium oxide began in the late 1950s. Four NIOSH Divisions have beryllium-related projects: beryllium-related

Beryllium Concentrate AMERICAN ELEMENTS
Beryllium concentrate is similar to powder in that it is made up of minute, dry particles of pure substance. Concentrate is also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. Our standard Concentrate particle sizes average in the range of 325
