  • 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 ...
