Ion Selective Ammonia (ISE) design

Pollution and Process Monitoring have optimised the Ion Selective Ammonia (ISE) design especially for applications containing suspended solids. The ProAm analyser has an integral peristaltic sample pump (capable of delivery a sample directly from source) which continuously delivers sample through large diameter tubing to a reaction vessel containing the ISE. The sample is then pH adjusted and agitated using an air-sparging system to liberate free ammonia for analysis. The internal tubing and the ISE is chemically cleaned using an automatic acid wash sequence at a user selectable interval (typically daily). This sequence removes any biological growth and calcification which can otherwise result in blockages. Emphasis has been placed on designing a measurement system which is simple, compact, robust and repeatable. Above all, reliability of operation has been the main objective.
