Cat.No. 114729  Spectroquant® Phosphate Cell Test
Cat.No. 116754  Water for analysis
Sample preparation:
Cleaning solutions contain, beside from pebble brine (highly disperged silicic acid), condensed phosphates and soluble phosphorus acidic ester. In a standard volumetric flask dilute the sample according to the expected
P-content 1:100 to 1:200 with water for analysis and filter it.
Determine with the above mentioned test kits.
Multiply the analysis value with the factor of dilution of the sample The result is equal to phosphorus (total) content in the original sample.
