1. a method, comprising:

  • By first measured zone introducing microfluid system at least partially of fluid sample;

    Measure the light transmission by the fluid sample at described first measured zone place or absorptivity;

    Form the signal corresponding with the fluid sample at described first measured zone place, the intensity of wherein said signal indicates the fluid sample at described first measured zone place, and the duration of wherein said signal indicates volume and/or the flow rate of fluid sample described in described first measured zone place;

    AndAt least in part based on the information drawn from the intensity of one or more signal and/or duration, determine whether to regulate the fluid in described microfluid system to flow, and/or the exception in microfluid system described in warning user in ongoing analysis.
