<p>Solid phase microextraction and analysis of analytes in a fluid carrier is carried out within a housing (62) in which a fiber (46) is vibrated during microextraction. The housing (62) contains access device so that the carrier and analytes can be brought into contact with the vibrating fiber (46) during the extraction stage. According to the present invention, the vibrating device comprises a membrane (32), a solenoid for vibrating the membrane (32), a frame, a retainer mounted on the frame for holding the solenoid, a holder (34) for the membrane (32), and a retainer arm (36) having one end connected to the retainer and the other end attached to the holder (34). <IMAGE></p> |
