Abstract (en)
A microfluidic chip (1) used for determining the physical properties and/or the chemical nature of at least two microplastic particles (3, 26, 28) suspended in a water liquid sample (4), the microplastic particles (3, 26, 28) having a size smaller than 200 micrometers, which comprises a first microfluidic channel (13) in which the microplastic particles flow, at least one filter (23) allowing the trapping of the microplastic particles (3, 26, 28) in the flow to accumulate the microplastic particles (3, 26, 28) in at least one stop area (24) on the filter (23), the filter (23) a being pattern engraved on the microfluidic chip (1), at least one output (19) downstream the filter (23), to exit the water sample (4) without the microplastic particles (3) from the microfluidic chip (1).
