Question
Can Amino Acid Powder Pillows be used in place of Amino Acid Reagent in orthophosphate method 8178?
Summary
Using Amino Acid powder pillows in place of reagent solution
Answer
The Amino Acid Reagent Powder Pillows for LR Silica (Product #s 80499 and 80428) can be used in place of the Amino Acid Reagent (Product #s 193432 and 193449) in method 8178 for orthophosphate. Results may be up to 5% high when using the power pillows because the Hach program accounts for dilution of the sample from addition of the solution. It is recommended to validate the accuracy of the deviation by testing known concentration standards.
