Analysis of Volatile Organic Compounds in Water by EPA Method 8260 with The Stratum PTC and Solatek 72 Multimatrix Autosampler.
Purge and Trap concentration (P&T) along with Gas Chromatographic (GC) analysis is a widely used method for the analysis of Volatile Organic Compounds (VOCs). This methodology was developed to achieve the high sensitivity necessary to determine VOCs in drinking water and other matrices according to United States Environmental Protection Agency (USEPA) Method 8260 as well as 524.2, 502.2, 601, 602 etc. To accommodate the requirements of USEPA Method 8260, Teledyne Tekmar has continually improved P&T technology by introducing new generations of enhanced concentrators into the analytical arena. The new Stratum PTC offers innovative U-shaped analytical and condensate traps, providing improvements over earlier P&T concentrators, therefore demonstrating excellent data results for many current USEPA methodologies. In addition to introducing the Stratum PTC and U-shaped traps, Teledyne Tekmar has developed a proprietary #9 trap for improved chromatographic performance on early eluting compounds found in many of the aforementioned methods. In this study water sample analysis was performed and linear calibration was demonstrated for 95 target analytes over the range of 0.5-200ppb. A 5mL purge volume was utilized, using conditions and specifications outlined in USEPA Method 8260. The Stratum PTC and Solatek 72 in conjunction with an Agilent 6890 GC and 5973 MSD are excellent tools for the identification and quantification of VOCs in water matrices.
