METHOD FOR IDENTIFYING THE PHASE OF A FLUID SAMPLE IN A MICROFLUID DEVICE

摘要

The invention relates to a method for identifying, by means of electrowetting or dielectrophoresis, the liquid or gas phase of a fluid sample (2) located in a confined microfluid system (1). According to the invention, two light signals, which come from the fluid sample (2) before and during the generation of an electrical field suitable for modifying the form and/or position of said sample (2) in the event that said sample consists of an electrically conductive or polar liquid, are compared.
