Dionex Demonstrates Simultaneous Determination of Anions and Cations in Saline and Drinking Water Matrices
Dionex announced a new method that easily resolves common anions and cations present in saline and drinking water in 20 min. Application Note 260: Monitoring Inorganic Anions and Cations During desalination demonstrates that the IonPac® AS18 and CS12A columns allow sample analysis with minimal sample pretreatment and maintenance during operation.
This new method also generates less waste and uses less eluent, thus saving both time and money. This approach provides good resolution between sodium and ammonium, the two analytes that can be challenging to resolve. This method supports a varying range of matrices from seawater to drinking water and is shown to be robust for all ion monitoring needs of a typical desalination facility.
With the growing demand for water and the limited supply of fresh water, desalination is increasingly being used to produce potable and irrigation water from salty or brackish water. The global market for desalination is projected to grow at an annual rate of 10% over the next 10 years. To optimize processing efficiency and meet regulatory requirements, it is critical to monitor anions and cations at all stages of desalination.
