Analytical Method: Analytical Quality Assurance, Standard for Nonionic Surfactants

 
Reagents:

Cat.No. 112298  Triton® X-100
Cat.No. 116754  Water for analysis
 
Preparation of a standard solution:
Dissolve 1.00 g of Triton® X-100 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 non-ionic surfactants.
 
Further investigational concentrations may be prepared from this stock solution by diluting accordingly.
 
Stability:
When stored in a cool place (refrigerator), the stock solution remains stable for one month. The diluted investigational solutions must be used immediately.
 

For use with test kits:
