Hanna HI4015-00 Sulfide Antioxidant Buffer (SAOB)
The Hanna HI4015-00 Sulfide Antioxidant Buffer (SAOB) is a specially formulated Ionic Strength Adjuster (ISA) designed for use with sulfide ion-selective electrodes (ISEs). This solution not only stabilizes the ionic strength in samples and standards, but also acts as an antioxidant buffer to prevent the oxidation of sulfide ions during analysis.
ISA solutions like the HI4015-00 are essential for accurate ISE measurements, as they ensure that the electrode measures ion concentration rather than ion activity. Additionally, the SAOB formulation helps to eliminate interference from competing ions and maintains the proper pH for sulfide ion detection.
Features
Dual-Function Buffer: Serves as both an ISA and an antioxidant buffer for sulfide ion measurement.
Stabilizes Ionic Strength: Ensures consistent ionic strength across all samples and standards for accurate concentration readings.
Prevents Sulfide Oxidation: The antioxidant properties protect sulfide ions from degradation during analysis.
Interference Reduction: Helps eliminate interferences caused by competing ions in the sample.
pH Conditioning: Maintains optimal pH range for accurate sulfide detection.
