concept of solid-phase microextraction (SPME) based upon the principle of partitioning of analytes between the extracting phase and the matrix (air, water and so forth). Many have developed modifications of this extractive approach and associated devices to improve the availability and application of this sample preparation technique.2 Among those approaches, SPME has been implemented practically by placing the fibre in a micro-syringe. This approach has been commercialized by Supelco (Bellefonte
