SMS-22 Sulfide Ion Analyzer
Brand: Electro-Chemical Devices (ECD)The ECD SMS-22 Sulfide Ion Analyzer is an all in one sulfide ion analyzer for the continuous measurement of sulfide ions in aqueous media.
Sulfide is present in well water, municipal wastewater and waste waters from refineries, tanneries, chemical plants, and paper and pulp facilities.
The ECD SMS-22 Sulfide Ion Analyzer uses a sulfide ion selective electrode (ISE) to measure the total amount of sulfide present in the sample.
The measurement must be made at high pH levels where S-2 exists.
Potassium hydroxide (KOH) is added to raise the pH of the sample to around pH 13 and a pH electrode measures the actual pH.
Sulfide and bisulfide exist in a pH dependent equilibrium with the ratio of each dependent on the pH.
The sulfide Ion Analyzer measures the sulfide present in the sample and the pH measurement infers what percentage of the total sulfide was measured. The C22 calculates and displays the Total sulfide present.
Features- Compact all in one measurement system.
- ISE based Sulfide Ion Measurement.
