Abstract : The objective of this research effort was a laboratory investigation of field-portable technology to demonstrate that available analytical methods for volatile aromatic hydrocarbons can produce data of known quality in a timely, cost-effective manner. Based on the results of a literature search, which was made to identify current field analytical techniques for the detection of benzene, toluene, ethyl benzene, and xylene (BTEX) in environmental samples, four promising technologies were selected for laboratory evaluation. No single field methodology was found to be superior to others; each method has advantages and disadvantages. Guidelines for choosing proper analytical methods for specific problems was provided. Also presented was method performance along with advantages and limitations for the procedures investigated.
