Description

Analysis Note US EPA Method 8260 describes the analysis of volatile organic compounds in solid wastes and ground waters. This application illustrates the analysis of many compounds commonly analyzed by this method using purge and trap coupled to GC-MS. A short, narrow I.D. SPB-624 column was used to shorten the analysis time to under 11 minutes. A high desorb flow through the trap was necessary to prevent band broadening of the gaseous VOCs. This was accomplished by increasing the split ratio, thus increasing the total flow through the trap during desorb.
