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.

摘要： In a general aspect, a sample is collected using a biological sampling apparatus. The biological sampling apparatus includes a shell having a closed end and an open end. The biological sampling apparatus also includes a harvesting tool comprising a shaft and a head. The shaft terminates in the head. The biological sampling apparatus additionally includes a translator configured to move the harvesting tool through the open end between a retracted position, where the head resides in the shell, and an extended position, where the head and at least a portion of the shaft reside outside the shell. A sealing member resides at the open end. The sealing member is configured to contact a subject surface and to create an enclosed sampling volume when collecting a specimen.
