Analytical Method: Analytical Quality Assurance, Standard for Hydrazine

Reagents:
Cat.No. 104603  Hydrazinium sulfate for analysis
Cat.No. 116754  Water for analysis
 
Preparation of a standard solution:
Dissolve 4.07 g of hydrazinium sulfate with oxygen-low (boil previously) distilled water in a calibrated or conformity-checked 1000-ml volumetric flask and make up to the mark with distilled water. The stock solution prepared according to this procedure has a concentration of 1000 mg/l hydrazine.
 
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 further diluted investigational solutions remain stable for one day.

 

For use with test kits:
