Product Description

AMT-I-C-006 Rapid Chem Phosphate(Ortho) (7 ML) (5-100 ppm)

AMT RAPID Chem Phosphate(Ortho) Test provides a fast and reliable method for the detection and quantification of orthophosphate present in the natural water, potable water, and industrial water. This method is compatible with Hach DR series photometers for absorbance measurement. Diagnostic reagents are preserved in a self-filling vacuum ampoule with extended shelf-life. Phosphate(Ortho) concentrations are represented as ppm (part per million). Each box includes 30 stand-alone tests.

Methods

This method is a convenient application of the technology in EPA method No. 70507, described in EPA Method 365.2 to determine total orthophosphate ion in waters. Orthophosphate ampoule contains potassium antimony tartrate, and ammonium paramolybdate reacting with orthophosphate to form an antimony-phospho-molybdate complex, which is reduced by ascorbic acid an intense molybdenum blue. The color is proportional to the phosphorous concentration.
