Disclosed herein is a system for desorbing and detecting an analyte sorbed on a solid phase microextraction (SPME) device. This SPME device The system includes a desorption chamber containing solvent required for desorption of analytes from SPME device; 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 SPME device can be configured to be various morphologies such as, fibers, blades, thin film membranes and even magnetic particles. When magnetic particles are used an additional holder that contains an embedded magnet which holds a plate with a well to hold said magnetic particles is added to the system.
