The ENEA Environmental Biogeochemistry Laboratory has been working since time in the development of innovative methods in the field of environmental analysis, aimed at the quality and reliability of the collected data, but also at saving time and costs. The aim is to develop and test new methods and portable analytical instruments and investigation techniques that are inexpensive, fast and easy to use for in field measurement, which, through a proper screening allow reliable results with only few samples subject to validation by more time consuming and costly laboratory analyses.
