Abstract: A system and method for analyzing volatile organic compounds (VOCs) adsorbed on an adsorbent membrane, by low-temperature plasma and mass spectrometry (LTP-MS). The system includes a receptacle for receiving the adsorbent membrane, a low-temperature plasma ionizer configured to emit a plasma stream in a plasma emission direction, thereby ionizing the VOCs adsorbed by the membrane and forming a VOC-laden ionized gas, and a mass spectrometer for analyzing the ionized VOCs.

Abstract: The invention concerns a method for determining at least one target molecule map in a tissue section, using at least one (A-X)n-B conjugate, wherein A is a tag molecule of known molecular weight, X is a linker that is cleaved during sample desorption/ionization, n is an integer of at least 1, and B is a binding molecule that binds specifically to said target molecule. When using MALDI mass spectrometry, said linker molecule X may be cleaved by photodissociation during sample laser irradiation if photocleavable at the wavelength of said MALDI laser. Alternatively, when using UV-MALDI, IR-MALDI, SIMS or DESI mass spectrometry, said linker molecule X may be cleaved by fragmentation during sample desorption/ionization.
