摘要: In a general aspect, a swab sample is analyzed, for example, to test for disease. In some examples, a swab head of a swab sample is inserted through an opening into an internal reservoir of a sampling device. The sampling device includes the opening, an inlet channel, an outlet channel, and the internal reservoir. The internal reservoir is in fluid communication with the inlet channel, the outlet channel, and the opening. A liquid solvent is supplied to the swab head in the internal reservoir via the inlet channel of the sampling device. The swab head is held in the liquid solvent for a period of time to form an analyte in the internal reservoir. The analyte is extracted from the internal reservoir via the outlet channel of the sampling device. The analyte is transferred to and processed by a mass spectrometer to obtain mass spectrometry data.
