Abstract (en)
[origin: WO2020064987A1] The present invention relates to a microfluidic method for analysing a fluid containing a metal trace element, in particular arsenic, comprising the following steps: a) introducing a fluid sample into at least one micro-channel of a microfluidic circuit; b) mixing, in the micro-channel of the microfluidic circuit, the introduced fluid sample with nitric acid and L-cysteine; and c) measuring the quantity of metal trace element present in the sample using an electrochemical detection method.
