We are at w ork on introducing new m ethod o f measuring c-8 level o f w aste w ater at Shimizu lab. TWF022431 EID514545 Traditionally m ethylene blue method has been used for this purpose here. For my understanding, you are involved in c-8 analysis at w w lab. And ec d c c is used for m easuring the c-8 level at w w . Now we are planning to install ECD Gas chrom atography apparatus as our new method. For purchasing new e c d g c at Shimizu, any your com m ent o r advise would be appreciated. Thank you in advance.
