Analytical Method: Analytical Quality Assurance, Standard for Oxygen scavengers

Cat.No. 818473  N,N-Diethylhydroxylamine for sythesis
Cat.No. 116754  Water for analysis
Preparation of a standard solution:
Dissolve 1.00 g of N,N-diethylhydroxylamine with 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 DEHA.
Further investigational concentrations may be prepared from this stock solution by diluting accordingly.
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:
