The Rio Symposium on Atomic Spectrometry (RSAS) and the Brazilian Meeting on Chemical Speciation (EspeQBrasil) are traditional events in their respective areas, and have been held every two years. The RSAS and EspeQBrasil had their last edition held in 2023 in the city of Bento Gonçalves (RS) and have already passed through several Brazilian stares or different countries.

EspeQBrasil was conceived by Professor Marco A. Z. Arruda, with the understanding that due to the growth of the field of chemical speciation, it would be important to have a forum to disseminate advances in the understanding of the biological and environmental functions of chemical species, the need for interdisciplinarity to understand these aspects, and the need for interaction between research groups in various areas of science. EspeQBrasil has already been organized in Rio Grande do Sul, Bahia, Paraná, and the state of São Paulo. This makes EspeQBrasil the ideal opportunity for the exchange of knowledge and dissemination of advances in these areas, as well as a business opportunity and contact with potential clients for the sponsoring companies.

After the COVID-19 pandemic period, which prevented these events from taking place in 2020, 2021 and 2022, EspeQ was resumed jointly with RSAS in 2023, in the city of Bento Gonçalves (RS), and now, both will be held in 2025 in the city of São Pedro (SP). Therefore, the organizing committees of these events invite your company to be a sponsor, helping us to maintain these fruitful interaction spaces, with business opportunities and prospecting for new potential customers.

The Organizing Committee has experience in organizing major events and will ensure a high-quality event, both from a scientific point of view and in terms of facilities for partner companies. We are available to discuss further and thank you for your support.
