Analytical Method: Analytical Quality Assurance, Standard for Total Chlorine

Reagents:
Cat.No. 102426  Chloramine T for analysis
Cat.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.
