Within the framework of IPERION-CH, a program that supports the creation of new mobile instrumentation, Laser-induced breakdown spectroscopy (LIBS), laser-Induced Fluorescence (LIF), Raman Spectroscopy and diffuse reflectance spectroscopy were combined to provide simultaneously elemental and molecular complementary information from the same analysis point. The prototype has been implemented for cultural heritage applications on Müstair Monastery mural paintings in the context of Molab European transnational access of IPERION-HS . We demonstrated through previous work the analytical possibilities of this instrumentation on mock-up and several cultural heritage materials and we also described the design and the implementation of the set-up that has been developed taking into account the heritage science constrains. At Müstair Monastery, the first implementation of this new analytical instrumentation on real site has been achieved. This paper will focus on the discussion on the advantages and limitations of this instrumentation in this specific context and the improvement in the development.
