Abstract
The present invention relates to a microfluidic method for analyzing a fluid containing a metal trace element, in particular arsenic, comprising the following steps of introducing a fluid sample into at least one micro-channel of a microfluidic circuit; mixing, within the micro-channel of the microfluidic circuit, the introduced fluid sample with nitric acid and L-cysteine, and measuring the quantity of metal trace element present in the sample, using an electrochemical detection method.
Claims13
A microfluidic method for analyzing a fluid containing at least one metal trace element comprising the following steps:
- a) introduction of a fluid sample into at least one microchannel of a microfluidic circuit;
- b) mixing, within the microchannel of the microfluidic circuit, the fluid sample introduced in step a) with the reagents, and
- c) measuring the quantity of the metal trace element present in the sample obtained in b), using an electrochemical detection method,
- the said step c) comprising mixing the sample obtained in b) with at least one solution comprising a metal trace element of known concentration, and then assaying the metal trace element by electrochemical detection method.
