Abstract: A mass spectrometry target assembly for accommodating at least one analyte (1) for mass spectrometry is provided, said assembly comprising: a target substrate (10) having a substrate surface (11), at least one measuring element (2), wherein said target substrate (10) and said measuring element (2) are different components, said measuring element (2) is fixed to said substrate surface (11), and wherein an electrical contact (12,16) is provided between said measuring element (2) and said target substrate (10) and/or said substrate surface (11). Because said target substrate (10) and said measuring element (2) are different components, said measuring elements (2) can be fabricated separately from said target substrate (10) and a material for said target substrate (10) can be chosen independent from the material used for said measuring element (2).
