Performance Demonstration of a Modern GC-MS Instrument and Novel BFB Tune for Analysis of Volatile Compounds by EPA Method 624.1 and 8260C.

The Clean Water Act of 1972 created the initial pathway for regulating the discharge of pollutants in water bodies in the United States. Since then, the United States Environmental Protection Agency (US EPA) has developed several analytical methods for monitoring Volatile Organic Compounds (VOCs) in water and other environmental matrices. EPA method 8260C is suitable for the analysis of VOCs in solid waste matrices. On the other hand, EPA method 624.1 is approved for analysis of purgeable organics in municipal and industrial wastewater. The standard operating procedures for both methods are similar, but the list of targeted compounds from each method includes different analytes. Overall, method 8260C is more comprehensive than method 624.1 because of its larger list of VOCs and approved sample types. While 8260C and 624.1 methods and their use on conventional GCMS have been successful, recent improvements of instrumentation require a reevaluation of the original method on newer instruments to demonstrate that the performance requirements included in these methods are met. This poster presents results from a demonstration study to determine Method Detection Limits (MDLs) for VOCs analysis by both methods 8260C and 624.1, using the newly released Shimadzu GCMS QP2020 NX and novel BFB tuning algorithm .
