<p>A portable plasma based diagnostic apparatus comprising a plasma source for producing energy projectiles at at-mospheric pressure, a mass analyzer, a sampling interface for receiving direct sample to be analyzed, the sampling interface being positioned between the plasma source and the mass analyzer, a database containing a library of biomarkers with their associated mass spectra, a processor operatively connected to the plasma source, the mass analyzer and the database The processor is so con-figured so as to obtain from the mass analyzer a sample mass spectrum of parent and fragment ions resulting form the collision be-tween the energetic projectiles and the sample, compare the sample mass spectrum with mass spectra in the reference library in or-der to identify at least one indicator and provide a report based on the at least one identified indicator</p> |
