The invention relates to a method for the spectrometry, in particular mass spectrometry, ion-mobility spectrometry, or optical emission spectroscopy, of a sample, comprising the following steps: providing a solid-state generator for generating a high-frequency signal, having a control element for varying the power and/or frequency of the signal, providing a plasma ignition head fed by the signal for generating a plasma jet, applying the plasma jet to a sample, performing a first measuring operation, wherein the plasma jet is generated with a first power of the solid-state generator and a spectrum emitted by the sample, preferably charged ions and/or optical spectrum, is recorded by means of a spectrometer, wherein the first power leads to a soft ionization of the sample, and performing a second measuring operation on the same sample, wherein the plasma jet is generated with a second power of the solid-state generator and a spectrum emitted by the sample, preferably charged atoms and/or optical spectrum, is recorded by means of the spectrometer, wherein the second power leads to a hard ionization of the sample.
