A device for carrying out solid phase microextraction on-site is a tubular member having one closed end and one open end with an extracting surface within said tubular member. The extracting surface can be an extracting phase coating extending over a zone within the tubular member. The tubular member is mounted in a housing with an airtight cavity. A method of operation of the device is also provided. The solid phase microextraction device facilitates the ultimate goal of chemist to perform analysis on-site at place where a sample is located rather than moving the sample to laboratory, as it is a common practice in many cases at present. This approach eliminates errors and reduces the time associated with sample transport and storage and, therefore, it results in more accurate, precise and faster analytical data.
