Analytical Services



The concentrations of Volatile Organic Compounds (VOCs) are determined using purge & trap extraction followed by Gas Chromatography-Mass Spectrometry (GC-MS). For Gasoline Range Organic (GRO) analyses, Gas Chromatography-Flame Ionization Detector (FID) is used. RTI Laboratories provides analysis of volatile compound lists ranging from limited subsets, such as BTEX analytes, to full target compounds lists per client request.

Different methods are utilized for the varying sample matrices. EPA method 8260C is used for the analysis of surface water, ground water and solid samples, while EPA method 624 is used for wastewater samples. EPA method 8015D is used in the analysis of soil and water samples for GRO compounds. RTI is able to analyze soil samples for low-level VOC concentrations using various collection techniques and can perform high-level analyses in methanol preserved samples.
