Disclosed herein is a system for desorbing and detecting an analyte sorbed on a solid phase microextraction (SPME) device. The system includes a desorption chamber sized to accept the SPME device while defining a void volume of less than about 50 μL; a flow injector in fluid connection with the desorption chamber, the desorption chamber and the flow injector being fluidly connected by at least a flow-insulating fluid connector; a solvent source in fluid connection with the flow injector; and a fluid switch that: in a desorption position, allows the solvent to be sprayed from the flow injector while flow-insulating any desorption solution in the desorption chamber, and in an detecting position, turns off the solvent source while maintaining the fluid connection between the flow injector and the desorption chamber, transferring the desorption solution through the flow-insulating fluid connector to the flow injector as a substantially undiluted plug of liquid.

The present disclosure provides for sampling instruments and methods of collecting sample particles. The sampling instrument can include a high-pressure pulsed valve coupled to a gas flow system to displace a sample from a surface. Also included can be a voltage supply coupled to a voltage switch, a suction device, a sample collector, and a collection filter. To collect a sample, extractive particles can be deposited onto a sample present on a substrate. At least a portion of the sample becomes coupled to a portion of the extractive particles to form sample particles. High-pressure gas can be discharged at the sample, thereby aerosolizing a portion of the sample particles to disperse aerosolized sample particles. A portion of the aerosolized sample particles can be collected onto a collection filter to form a collected sample.
