ipaMS is a collaboration of university research groups, and the daily life of the scientists, which form ipaMS is exactly that: Research and scientific work, driven by the desire to fundamentally explore natural phenomena related to mass spectrometry.

In the following is a list of conference posters (each with a pdf download link) of the last 8 years, which gives a good impression of this driving force and the emerged projects worked on by ipaMS members.
