In this paper a new prototype of solid phase microextraction–ion mobility spectrometry (SPME–IMS) system was developed to effectively couple the extraction efficiency of SPME with the detection capability of IMS. The main component of this system was the transfer line/desorber, which was a low-thermal-mass (ca. 0.15g) silicosteel coatings stainless steel tube. The transfer line/desorber was designed...
