The Environmental and Biological Mass Spectrometry Group (GEMAB), has the main goal of applying mass spectrometry to solve analytical problems, to study environmental and biological systems as well as to study gas-phase ion reaction and mechanisms, reactivity, ion structures and ion thermochemistry.  GEMAB is one of the 12 groups of Centro de Química e Bioquímica, CQB, a research unit of Departamento de Química e Bioquímica, DQB, of Faculdade de Ciências da Universidade de Lisboa, FCUL, dealing with the study of a wide range of topics in chemistry and biochemistry many of which fosters strong group interactions.

The Scientific Coordinator of GEMAB group, Maria Helena Florêncio, formerly the Scientific Coordinator of CEM and responsible for one of ithe  two research areas of CEM, is a Full Professor in Analytical Chemistry and since 2006 the head of the National Mass Spectrometry Network, RNEM, a network that has been included in the Roadmap of Scientific Infrastructures under implementation by FCT.

 The main research topics of GEMAB, liested below, are integrated within regional and national concerns :

  • environmental studies aim to study some issues that affect the country’s flora, the aquatic environment and how to address solutions concerning water pollution and polluting agents.
  • to correlate traditional knowledge with scientific aspects concerning functional foods on what concerns compounds identification, effect of the cell metabolism on the bioactivity of the compounds and the effect of these compounds on cellular metabolism (metabolomics)
  • Development of metrological models able to estimate the cause for forest fires is also of major relevance for our strategy as the country is often devastated by this problem during summer season.
  • Development of materials as interference-free MALDI matrices is also a technological application which is expected to lead to commercial use.


Financing of the Group: Pluriannual CQB financing and  research projects

Main Equipment:  LC-DAD; GC-MS; LC-MS; and access to the FT ICR-MS (Main equipmente of FCUL node of RNEM)
