Sample(s)

The following analysis were performed with standard solutions.

Conditions

Conditioning: 5 mL methanol, 5 mL sulphuric acid (0.05 M)

Sample application: 10 mL standard solution in aqueous or methanolic sulphuric acid (0.05 M) with a flow rate of 3 mL/min

Washing: 6 mL water with a flow rate of 3 mL/min or 6 mL methanol with a flow rate of 3 mL/min

Drying: 5-10 min with vacuum

Elution: 2 x 5 mL 2.5 % ammonia in methanol

Eluent exchange: Evaporate eluate to a volume of 0.5 mL at 40 °C under a stream of nitrogen and fill up to 1.0 mL with water - methanol (95:5, v/v).
