摘要
A method and analytical device for collecting a sample volume containing at least one analyte of interest from a liquid analytical sample having contaminants disposed at or near the sample surface. The liquid analytical sample is provided. A first pipetting device comprising a first pipetting needle aspirates from an upper region of the liquid analytical sample a portion comprising the contaminants and discards the portion. The first needle is washed with washing liquid. A second pipetting device comprising a second pipetting needle, or a disposable pipetting tip, aspirates the sample volume from the liquid analytical sample after the first pipetting device discards the aspirated portion and discharges the sample volume for analysis. The second needle is washed with washing liquid or disposed of.
