For the time being, we do not have to exchange methods that you are still in the process of exporing or evaluation. Please send the english translations of all your standardized methods for C-8 in water to Steve Peck at WW and Kitagawa-san at Shimizu. In the coming week, we should try to start working on how to converge to a set of standardized methods. As far as timing is concerned, we certainly would like to get your english translation version soon, but we have room to accomodate your other priorities. How about in the next 3 weeks ? Thanks.

Cor De Heer/EUR/DuPont@DuPont C8 analyses in waste water Ta-Wei, 1 We will translate our GC-ECD method for C8 in waste water and send it to you. When do you need the translation? ppm, %linear + % branched) into english 01 We also have other methods for c8 like GC-FID (>1 ppm, %linear + % branched), uv-vis titration (KC8 > 100 ppm). Are these methods also part of the convergence? ppm) and Regards, Francois TWF022544 EID514658
