Abstract:
1. A method for analyzing at least one reaction medium comprising at least one cell C, comprising: (i) depositing at least one reaction medium containing the cell C onto a support S comprising a substantially planar surface and contained within a controlled atmosphere chamber, in the form of aqueous drops comprising the cell C and a solution of culture medium on said surface; (ii) covering the substantially planar surface of the support S onto which the aqueous drops containing the cell C has have been deposited with a separating film F that allows gases to pass through and prevents evaporation of the aqueous drops deposited onto the support S; (iii) growing the cell on the planer surface of the support S; (iv) optionally applying to the aqueous drops containing the cell C one or more treatment steps; (v) preparing and introducing the support S contained within the controlled atmosphere chamber and supporting the reaction medium into a mass spectrometer; (vi) desorbing and ionizing the reaction medium in the mass spectrometer; and (vii) recording and analyzing the mass spectrum of the reaction medium.
