Method Performance
Typical Precision (95% Confidence Interval):
1.0 ± 0.04 mg/L
Estimated Detection Limit:
EDL = 0.02 mg/L
Silica
Greater than 50 mg/L
Silicate
Greater than 10 mg/L
Turbidity (large
amounts) or color
May cause inconsistent results because the acid in the powder
pillow may dissolve some of the suspended particles and
because of variable desorption of orthophosphate from the
particles. For highly turbid or colored samples, add the contents
of one Phosphate Pretreatment Powder Pillow (Cat. No. 14501-
99) to 25 mL of sample. Mix well. Use this solution to zero the
instrument.
Zinc
Greater than 80 mg/L
