Nowadays Mass Spectrometry is an indispensable and important technique in many analytical laboratories. The mass spectrometry instrumentation has evolved exponentially in the last few decades and many new advances are now being used in an increasing number of research centres, companies and hospitals around the world. The growing number of installed instruments grows together with the increase of young people approaching to mass spectrometry. Unfortunately, the widespread use of mass spectrometry is not accompanied by a corresponding spreading and reinforcing of its culture. Although mass spectrometry in universities is taught more and more, in many countries the level has not yet reached the mature level of other disciplines. Young mass spectrometrists should be able to update their knowledge on the latest trends in instrumentation and applications in mass spectrometry.

Given this background, IMSF decided to extend and reinforce its action to higher education through the organization of the International Mass Spectrometry School (IMSS), which was originally proposed by the Division of Mass Spectrometry of the Italian Chemical Society and let to the organization of the 1st IMSS in Siena (Italy) in 2013. The success of this school brought to different national mass spectrometry societies to organize the IMSS biannually on behalf of the IMSF, thus alternating the IMSS with the International Mass Spectrometry Conference (IMSC). The Brazilian Mass Spectrometry Society (BRMASS) hosted the 2nd IMSS in Natal (Brazil) in 2015 and the Nederlandse Vereniging voor Massa spectrometrie (NVMS) worked together with the MSBM to host the 3rd IMSS in Dubrovnik (Croatia) in 2017. Continuing with this educational initiative and trying to consolidate it, the Spanish Mass Spectrometry Society (SEEM), on behalf of the IMSF, will host the 4th IMSS in Sitges (Barcelona, Spain) from 15th to 20th September 2019. On this occasion, SEEM has the support of the Spanish Scientific Societies of Chromatography and Hyphenated Techniques (SECyTA), Proteomic (SEProt), Applied Spectroscopy (SEA) and Analytical Chemistry (SEQA), in order to bring together in the 4th IMSS 2019 the maximum number of scientists working in multidisciplinary areas related to mass spectrometry.

IMSS 2019 is a six day full immersion school aimed to give advanced education in mass spectrometry to graduate, PhD, post-doc students and young working in the areas of chemistry, biosciences, food, environment and medicine. The school should also be useful for allowing meeting of young scientists coming from different countries and for creating new links among young generation of mass spectrometrists.
