Abstract
A micro-syringe for inserting into a sample matrix. The micro-syringe includes a micro-syringe body having an orifice at an insertion end; and a plunger at least partially coated with a solid-phase micro-extraction (SPME) coating. The plunger is longitudinally movable between an internal position and an extended position. When the syringe is inserted into the sample matrix, the extraction phase is shielded from the sample matrix by the micro-syringe body when the plunger is in the internal position, and at least a portion of the extraction phase extends past the orifice and is exposed to the sample matrix when the plunger is in the extended position. The plunger is sized to fit the internal diameter of the micro-syringe body to draw a liquid into the micro-syringe body when the plunger is moved from the extended position to the internal position.
