Do you need a recognized method or can you start with something published and go from there? If so things on google may help you, like http://www.google.com/url?sa=t&rct=j&q= ... hSZymRb_2A

The later looks at dioctyl phthalate, but diethylhexyl phthalate elutes near dioctyl phthalate. This may or may not give you the ability to see the concentration range you need...
