F ra n c o is, ' I think it will be very valuable for both W W and Shim izu to kn.ow all your available standardized C -8 analysis at Dordrecht a s our first step to m ove tow ard converging te st m ethods. For the tim e being, w e do not have to exchange m ethods that you are still in the process o f exporing or evaluation. Please send the english translations o f all your standardized m ethods for C -8 in w ater to Ste ve Peck at W W and Kitagaw a-san at Shim izu. In the com ing week, w e should try to start w orking on how to converge to a se t o f standardized m ethods. A s far as tim ing is concerned, w e certainly w ould like to get your english translation version soon, but w e have room to accom odate your other priorities. H o w about in the next 3 weeks ? Thanks.

W hen do you need the translation? W e also have other m ethods for c 8 like G C -FID ( > 1 ppm , % linear + % branched), u v-vis (> 1 p p m ) and titration (K C 8 > 1 0 0 ppm). Are these m ethods also part of the convergence? Regards, Francois TW F022544 E ID 514658
