Claim Text:
1. A method for detecting at least one compound present in fluids, said method comprising the following steps: a. providing at least one dried fluid spot on a support, b. fixing at least a part of said dried fluid spot on said support on a conductive surface, c. providing an aqueous or organic solution of a UV-light-absorbing compound, d. depositing said UV-light-absorbing compound on at least a part of said dried fluid spot on said support fixed on said conductive surface, e. subjecting at least an area of said dried fluid spot on said support to a Matrix Assisted Laser Desorption Ionization process to produce ions, f. acquiring a full scan mode mass spectrum of said ions by a mass analyzer and, g. determining a presence of the at least one compound by analyzing the full scan mode mass spectrum.
