Groundwater Control Analytical Standard

Standard samples of nonylphenol, 1,4-dioxane, and1,2-dichloroethylene used for Environmental Quality Standards for the Water Pollution in Base Environment Act in Japan are available. Nonylphenols are suspected to be endocrine disrupting chemicals. The quantitative analysis for it is carried out by solid phase extraction - GC/MS SIM method. 4-(3,6-dimethlyheputane-3yl)phonol-13C6, a related product, is also available.
