Mass spectrometry is a method for identifying the different atoms that compose a substance. A mass spectrometer bombards a substance with electrons to produce ions, or electrically charged atoms. The ions cross a magnetic field that curves their trajectories in different ways, depending on their mass. The field separates the ions in a pattern known as the mass spectrum. The mass and the charge of the ions can be measured by their position in the spectrum, thereby allowing the elements and isotopes present in the sample to be identified. The technique of mass spectrometry is of great importance for research groups that study biological processes, whether for the production of compounds of commercial interest or for the monitoring of environmental pollution. The identification of microbial products final or intermediate, is of fundamental importance for the advancement of such research. With equal needs and similar problems, research groups at the São Carlos School of Engineering (USP) and the Federal University of São Carlos (UFSCar) have been discussing and working to determine which equipment best meets the needs of the two groups, and, to that end, various meetings have been held and lectures have been given by specialists in the area of mass spectrometry. The objective is the acquisition of equipment that meets the needs of both groups. It is hoped that the acquisition of this equipment and the establishment of the technique will allow the respective research groups to conduct studies that are more in-depth and accurate, as well as allowing lines of research that had been abandoned (due to the lack of such techniques) to be reactivated.
