HI-4015-00 SAOB (SULPHIDE ANTIOXIDANT BUFFER)
HI-4015-00
HI-4015-00 is a buffer solution for use with Silver/Sulphide Ion Selective Electrodes. Comprising two components: one 500 mL bottle of SAOB Reagent A and one 18g bottle of SAOB Reagent B.
Hanna ISA solutions are formulated to fix the ionic strength of a sample and standards. Without addition of ISA, an Ion Selective Electrode measures ion activity. Addition of ISA stabilises the ionic strength and permits measurements as ion concentration. With some ISEs, the ISA solution is also used to adjust the solution’s pH or to remove any potential interference from competing ions present.
