Abstract Methodology was developed to reproducibly prepare performance evaluation materials for volatile organics analysis in soils and waters. Tedlar gas sampling bags are used to prepare the volatile organics spike solutions. The bags allow large volumes of sample or spike solution to be prepared to a high degree of homogeneity while using less methanol. Preparation of a large volume of sample or spike solution allows for increased accuracy of fortification. The accuracy is generally ±20% or better, and the precision is generally ±10% or better for water samples. The precision for preparation of soil samples is also good, but the accuracy suffers from variable recovery efficiencies from the soils. Most volatile organics were well preserved in 3 water samples by storage at refrigerator temperature for 14 days.

This paper describes a GC/MS system capable of performing Volatile Organic Analysis on liquids, solids, and air. When combined with a syringe auto-injector, the system is completely automated for both volatile and semi-volatile analyses. An OI Analytical Model 4551 Vial Multisampler and an OI Analytical DPM-16 Multisampler are interfaced and then connected to an OI Analytical Model 4560 Sample Concentrator, an HP Model 5971 MSD, an HP Model 7673 Auto-Injector, and an HP Model 5890 Series II GC to form a multi-tasking GC/MS system. This system is shown to allow greater versatility in the laboratory.
