Are there any chemists/scientists out there who have experience with the
new
SFE methods for sample extraction?  Sounds like the future to me- no more
methylene chloride (toxic/hazardous waste concerns/ozone holes!) or
acetone
(hazardous, flammable) to use and dispose of.  We shouldn't be creating
more problems than we are helping to solve by using these materials, that
is, if an approved alternative exists.  Today I received the Draft Method
for SFE that EPA might include in the next rev of SW-846, but it is just
that, Draft, not promulgated.
Does anyone know how to voice support for quicker promulgation of EPA
Draft Methods, or for implentation of more user-friendly (less toxic)
methods?

Please e-mail me if you need futher info;   davezale@aol.com,

Thanks for your help/interest.
