US EPA Method 325 sets out a protocol for monitoring refinery perimeters for hazardous VOCs such as benzene. Specifying two-week passive sampling with sorbent tubes followed by analysis using TD–GC, the method is scheduled to be implemented in mid-2015 as part of the updated US federal regulation CFR 40.
Now is the time to plan for how to comply with Method 325 – and Markes is uniquely well-placed to help you. We provide a complete solution package for Method 325, and can offer advice both on the technical aspects and on future developments and associated regulations.
