The present invention considers bringing a mobile unit closer to the site of interest and conduct the quantification of the tracers by performing the detection methods in situ and in real time at the wellhead, and that can be moved to the site on numerous occasions for the preparation of results during the test where the quantification of tracers is necessary, helping to speed up and reduce times that, until now, have not been achieved with stationary laboratories and that depending on the laboratory can last up to three months providing results.
