Leverandør: Lovibond
Provides accurate and reliable water analysis solutions that are valuable in a range of industries.
- Colours may vary depending on sample and test conditions
- Ignore any undissolved material after powder/tablet addition
- For concentrations of sodium sulphite above 150 mg/l take a 10 ml sample and use a factor of 10 (i.e. each drop of Sulphite Titrant S2 used = 10 mg/l Na2SO₃)
Catalysed sulphite reacts quickly with atmospheric oxygen when hot, so the sample should be cooled during collection with the minimum of contact with air. It should be tested immediately after it has cooled. Care should be taken when obtaining samples.
Sulphite reserve may be expressed in different ways. To convert readings from sodium sulphite multiply the result obtained by the following factors. Sodium sulphite to sodium metabisulphite×0,8 and sodium sulphite to sulphite×0,63.
