Um aplicativo web para controle de qualidade laboratorial aplicado à geoquímica

Abstract

Quality control applied to geochemistry is widely used as a tool for quality assurance and confidence in analytical results. In order to achieve continuous improvement in the laboratory and in the management of geochemical databases through the promotion of preventive or even corrective actions, in a more agile and safe way, it is essential to use technological tools to identify opportunities. In this context, interactive software emerges as allies, allowing data analysis with greater security and using a wide range of information, in addition to enabling data visualization through dynamic and interactive graphics. Given this scenario, the present work proposes the development of an application, easy to use, capable of providing essential information, such as analysis of control charts of reference materials, replicates, descriptive analysis of results and traceability to the analytical batch. To achieve this purpose, the application was built using the Shiny package from the R statistical computing environment. The great advantage of using this type of application lies in the simplicity of its use, eliminating the need for advanced programming knowledge. This way, users can explore the information contained in the data more intuitively and efficiently. With the implementation of this interactive application, a significant optimization of the processes for identifying improvement opportunities is expected, effectively contributing to the formulation of assertive and efficient actions. It is also possible to include several other types of quality control tools within the same platform. Furthermore, facilitated data visualization and the creation of targeted strategies will promote an environment conducive to the growth and development of activities.
