摘要:
The present invention is directed to an enhanced sampling device, herein referred to as an ESD, for enhancing the collection efficiency of the SPME method by enhancing the flow of the analytes onto the sampling fiber. The ESD includes a tubular main body, used for a sampling shroud, which directs a flow of analytes to contact the fiber during collection. One end of the main body is open and faces the sample, allowing analytes to flow into the ESD and contact the fiber. A second piece of tubing branches from the other end of the main body and becomes an outlet port, possibly leading to a pump. The ESD permits more rapid transport and absorption of the analytes to the fiber for collection.
