1. A method of analyzing fluid in a downhole environment comprising:

  • a) introducing a fluid sampling tool into a well bore that traverses an earth formation;

    b) using the fluid sampling tool to extract the fluid from the earth formation into a flow channel within the tool;

    c) monitoring an indication of contamination in the fluid while extracting the fluid from the earth formation and flowing the fluid through the flow channel; and

    d) when the indication of contamination in the fluid has stabilized, analyzing the fluid in the flow channel.
