Analytical Method: Analytical Quality Assurance, Standard for Total Chlorine

Reagents:

Product No. 102426 – Chloramine T for analysis
Product No. 116754 – Water for analysis

Preparation of a Standard Solution:

Dissolve 4.00 g of chloramine T with water for analysis in a calibrated or conformity-checked 1000-ml volumetric flask and make up to the mark with water for analysis. The stock solution prepared according to this procedure has a concentration of 1000 mg/l total chlorine.

Further investigational concentrations may be prepared from this stock solution by diluting accordingly.

Stability

When stored in a cool place (refrigerator), the stock solution and the diluted investigational solutions remain stable for one day.
