Abstract:
Gasoline Range Organics refer to hydrocarbons with a carbon range from C6-C10 that have boiling pointsranging from 600 to 1700 Celsius. These chemicals are frequently present in the environment especially in soils and ground water and the source of contamination is usually human errors or accidents (such as oil spills) that occur when handling, storing or transporting oil and oil products. If GRO are detected in soils or water, the level of contamination needs to be determined by using quantitative analytical methods. Often the method of choice is head space sampling techniques coupled to gas chromatography and mass spectrometry and/or flame ionisation detectors.
In this work, the Triplus Plus 500 valve-and-loop static headspace coupled with a Trace 1310 gas chromatographand an ISQ 7000 mass spectrometer were employed to develop an automated method for quantitative assessment of GRO in water. Chromeleon chromatography data system was used to acquire, process and report data. The performance of the method was assessed and various analytical parameters investigated. The data presented in this study demonstrates the method performance and reliability in addition to automated data processing and reporting capabilities.
