Reagents
Polyacrylat Reagent Set
KS336-Propan-2-ol
Cartouche C18
KS173-P2-2,4 Dinitrophenol Indicator
KS183-QA2-MO1-P3-Nitric Acid
Preparation
• Preparing the cartridge:
1. Remove the plunger from a suitable syringe. Attach the C18 cartridge to the syringe
cylinder.
2. Add 5 ml of KS336 (propane-2-ol) to the syringe cylinder.
3. Using the plunger, press the solvent by drop through the cartridge.
4. Remove the solvent that has passed through.
5. Remove the plunger again. Fill the syringe cylinder with 20 ml of deionised water.
6. With the help of the plunger, press the contents through the cartridge drop by drop.
7. Discard the deionised water that has flowed through.
8. The cartridge is now ready for use.
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.
2. Anomalous results occur when interferences are present as part of the sample
components or from sample contaminants. In this case, the interference will need to
be eliminated.
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.
