Phosphate standards will be prepared in the range from (ie.) 0.200, 0.500, 1.00, 2.00, 3.00 and 4.00 µg/mL in dH2O using the stock KH2PO4 solution (~50.00 µg/mL) in 50.00 ml volumetric flasks using volumetric syringes and pipettes ranging in volume from approx. 0.200 to 4.00 mL. *note : this range is a suggestion. Anything from 0.2 to 5.0 will work, as long as all 6 standards are distributed somewhat evenly between 0.2 and 5 µg/mL
