Sample holder for MALDI mass spectrometric analysis, and mass spectrometric analysis method

摘要

A secondary particle consisting of CuO primary particles of less than an average particle diameter of 100nm is to set, a MALDI mass having a CuO secondary particles having an uneven surface due to the shape of the primary particles constituting the outermost surface layer as a laser light-absorbing matrix use of sample holders for analysis. The CuO 2 primary particles, by air baking basic copper carbonate produced by the process of mixing the ammonium bicarbonate solution and an aqueous copper nitrate solution, at 200 to 300 ℃ can be used that derived from a CuO powder to be synthesized, the art CuO 2 primary particles is, for example, the average particle diameter of 0.3 to 10㎛. ; MALDI mass spectrometry sample holder, the mass analysis method for, CuO primary particles 1, 2 CuO primary particles
