One Mill – Many Possibilities

The FRITSCH Variable Speed Rotor Mill PULVERISETTE 14 classic line is the ideal mill for fast, effective comminution of soft to medium-hard, brittle and fibrous materials as well as temperature-sensitive samples – proven worldwide for the use in trace analysis. The motor speed can be varied between 6,000 and 20,000 rpm in increments of one-thousand – making it possible to adapt the mill to each specific application. An automatic speed compensation feature ensures an ideal adaptation of the grinding...

ERM-CZ110: a new Certified Reference Material for analysis of airborne particulate matter

Airborne particulate matter is a major problem in many densely populated areas of the world. This pollutant is a mixture of particles of different size and composition, originating from different sources. The finest fraction of these particles, the so-called PM2,5,, is notoriously dangerous because it can penetrate deep into the lungs and may pass into the bloodstream causing respiratory problems and premature death. In response, the European Union has developed an extensive legislation which establishes health...

This proposed action is taken in response to the United States Court of Appeals for the District of Columbia Circuit’s (D.C. Circuit) remand of the Cross-State Air Pollution Rule (CSAPR) Update in Wisconsin v. EPA on September 13, 2019. The CSAPR Update finalized Federal Implementation Plans (FIPs) for 22 states to address their interstate pollution-transport obligations under the Clean Air Act (CAA) for the 2008 ozone National Ambient Air Quality Standards (NAAQS). The D.C. Circuit found that the CSAPR...

New issues in air monitoring

Sulfur Dioxide (SO2 ) EPA air quality standards have developed a new National Ambient Air Quality Standard (NAAQS) for Sulfur Dioxide concentration averaged over a one-hour period. Historically, attainment status has been assessed using existing monitors located across the nation. However, due to the large number of affected facilities and a lack of adequate spatial coverage of the existing monitoring network, EPA has approved using a combination of both dispersion modeling and ambient monitors to demonstrat...
