Inquiry (采购产品): Wastewater analysis I would like to analyze the amount of sulfide and sulfate in the sample of mixture of wastewater which I believe it is quite complicated because it also contains HHT, HAM and heavy metals. I just wonder your company would be able to do this test as well as which method is applied. **** Hidden Message ***** Thy Nguyen QC H2X 3P4 CAN Company: Tecsult E-mail: thy.nguyen@tecsult.com **** Hidden Message ***** thy.nguyen@tecsult.com
