Dear Colleagues and students on behalf of the Organizing Committee, it is a pleasure to invite you to join us by registering at the forthcoming 23rd International Symposium on Pharmaceutical and Biomedical Analysis (PBA 2011), which will be held for the first time in Brazil.

The Symposium will take place at the city of João Pessoa, Paraiba, Northeast of Brazil, from 9^th to 12^th of October 2011.

PBA 2011 will provide a forum for the presentation and, above all, the exchange of information and technology among researchers/professionals interested in drug analysis at all levels.

The main purpose of this symposium series is to attract researchers from all areas involved in pharmaceutical and biomedical analysis. Thus, the topics selected for this version of the symposium will, as always, encompass a broad range of subjects, such as separation science, crystallography, electroanalysis, termoanalysis and bioimage, among others.

The symposium will be organized in a single session, with plenary and keynotes lectures given by outstanding scientists. The program will include oral and posters communications chosen on the basis of abstract selection. After the symposium, a special issue of the Journal of Pharmaceutical and Biomedical Analysis will be provided for publication, which will be peer-reviewed following its conventional rules.

Yours Sincerely,
