Can Amino Acid powder pillows be used in place of Amino Acid reagent solution for phosphate tests?
Using Amino Acid powder pillows in place of reagent solution
Yes, the powder pillows (catalog number/order code 804xx) can be used in place of the solution (catalog number/order code 194xxx) for the high range (HR) phosphate tests. However, the calibration will be off slightly because there is no dilution of the sample by the powder reagent. The readings will be about 5% higher.
