The Fleury Group's project consisted of the routine implementation of an innovative technology called Laser Diode Thermal Desorption (LDTD) coupled to a mass spectrometer for the quantitative analysis of vitamins A and E, and the hormone estrone. Measuring these vitamins is essential for diagnosing hypovitaminosis and hypervitaminosis, while estrone dosage is used in postmenopausal hormonal evaluation. The LDTD technology uses a laser to release molecules from dry samples that are analyzed by a mass spectrometer, eliminating the need for harmful organic solvents such as methanol and acetonitrile in the process. This results in a significant reduction in chemical waste generated, promoting sustainability and efficiency in clinical diagnoses. Furthermore, the technology has significantly increased productivity, reducing the analysis time for each sample from 10 minutes to just 15 seconds. The project's objective was to seek more sustainable alternatives that would increase productivity and reduce the environmental impact of laboratory processes, aligning with the ESG principles of the Fleury Group.
