Notes:
1. If little or no turbidity is present at correct dose concentrations, the sample will need a
pre-concentration step in order to detect this level of polyacrylate/polymer. Carry out this
procedure as directed then test the pre-concentrated sample as above (see next page).
2. Anomalous results occur when interferences are present as part of the product blend
or from sample contaminants. In these instances follow the interference removal steps
detailed below and test this treated sample as above (see next page).
3. This test has been calibrated using polyacrylic acid 2'100 sodium salt in the range
1-30 mg/l. Other polyacrylates/polymers will give differing responses and therefore the
test range will vary.
