- Sample(s)
A drinking water sample was taken according to DIN 38402. The sample was treated with 100 mg/L sodium thiosulfate pentahydrate to reduce oxidizing species. 40 mg/L sodium azide was then added to avoid microbiological degradation. An aliqout of 500 mL pretreated water sample was spiked with 50 ng acrylamide.
- Conditions
Column conditioning: 8 mL methanol, then 8 mL water
Sample aspiration: Sample was aspirate at a flow of 20 mL/min.
Washing: 1 mL water
Drying: 15 min nitrogen or air flow
Elution: 5 x 2 mL methanol
Concentration: Eluate was concentrated to 1 mL by heating at 40 °C under a slight nitrogen stream.
