HPR-40 MIMS System Assists in Denitrification Studies

Denitrification is the process carried out by bacteria that converts nitrites and nitrates to nitrogen, nitric oxide and nitrous oxide gases. Two of these gases have been linked with ozone layer depletion and global warming. Denitrification is an anaerobic process and occurs in environments where oxygen levels are depleted, such as within soils and groundwater. The Hiden HPR-40 membrane inlet mass spectrometer (MIMS), designed for the measurement of dissolved gas species, is ideally suited to the study of such processes and simultaneously and continuously measures multiple gas species in real-time down to ppb levels.
