CHNS Analysis of Particulate Matter in Natural Waters and Air

Elementar Logo



The ocean plays a monumental role in maintaining homeostasis on Planet Earth. The ability to accurately determine the contents of our natural waters and air within the environment is becoming increasingly paramount. Filter samples are distinct from other samples commonly analyzed by elemental analyzers. They often produce a lot of ash and are loaded with sample material containing low elemental concentrations, making the removal of ambient air blank very important and analysis challenging.
