Abstract
The present invention refers to a portable analysis system that, from analytical methodologies set based on digital images acquired by portable devices and accessories developed in an expedited way, allows the performance of the analytical test without technical deepening by the executor of the analysis. Such methodologies allow the evaluation of chemical species relevant to the O&G sector, for following up compositional parameters in aqueous samples and analytical monitoring of production and effluent treatment. Thus, a quick implementation is possible considering eventual diagnoses associated with the parameters of interest and following up of different processes. The application can be in any laboratory present in an operational unit, whether offshore or onshore, as well as it can be used for direct measurement in the field, depending on the necessary environmental and operating conditions.
