What are the known interferences with the CA610 analyzer?
Zusammenfassung
CA610 interferences
Antwort
The CA610 analyzer should have similar interference to other Lanthanum fluoride ISE probes. 
  • Cations should not interfere.
  • Chloride, Bromine, Sulfate, and Phosphate do not interfere.
  • Hydroxyl ions do not interfere when the sample is less than 8.
  • Alkalinity or PO4 3– do not interfere but can increase the Hydroxyl interference. 
Standard methods 4500 -F A has a comparison list of interferences with the electrode interference including to SPADNS.
