Abstract: Mass spectrometry systems include a core featuring an ion source, an ion trap, and an ion detector connected along a gas path, a pressure regulation subsystem connected to the gas path and configured to regulate a gas pressure in the gas path, a sample pre-concentrator connected to the gas path, where the sample pre-concentrator includes an adsorbent material, and a controller connected to the sample pre-concentrator, where during operation of the system, the controller is configured to heat sample particles adsorbed on the adsorbent material to desorb the particles from the adsorbent material and introduce the desorbed particles into the gas path, and a pressure difference between a gas pressure in the sample pre-concentrator and a gas pressure in at least one of the ion source, the ion trap, and the ion detector when the desorbed particles are introduced into the gas path is 50 mTorr or less.
