The information on the sample preparation presented here is not sufficient for use in the laboratory. For a detailed step by step description, please refer to the instruction manual.

• Pipette 200 µl of the sample/calibrator/MassCheck® control into each Sample Clean Up Column.
• Add 50 µl Internal Standard Mix and 600 µl Neutralisation Buffer.
• Check for correct colour.
• Centrifuge 5 min at 150 x g, discard effluent.
• Add 0.9 ml Wash Buffer 1 and centrifuge 5 min at 150 x g, discard effluent.
• Add 2 x 0.9 ml Wash Buffer 2 and centrifuge each time 1 min at 150 x g, discard effluent.
• Centrifuge 1 min at 2000 x g to dryness, discard effluent.
• Put Sample Clean Up Columns on new glass collection vials (e.g. glass autosampler vials).
• Add 500 µl Elution Buffer and centrifuge 2 min at 100 x g.
• Add 500 µl Dilution Buffer to each glass vial.
• Seal each glass vial.
• Shortly vortex each glass vial and transfer vials to autosampler.
• Inject up to 10 µl.
