Publication number: 20180038840Abstract: The invention is directed towards a method and system for optically-based monitoring of chemicals of potential concern (COPCs), including mercury (Hg), methyl mercury (MeHg), and polychlorinated biphenyls (PCBs). It employs a multi-parameter statistical analysis model, such as partial least square regression (PLS regression), to identify combinations of predictors (e.g., optical, water quality, and physical properties) that have large covariance with the response values. The predictive model is validated against analytic samples from laboratories. The steps in the method are repeated until predictors, or parameters are selected that avoid over-fitting and which yield physically-based results.Type: ApplicationFiled: June 26, 2017Publication date: February 8, 2018Applicant: Integral Consulting Inc.Inventors: Grace Chang Spada, Craig A.

Publication number: 20180038841Abstract: The invention relates to a component, comprising a carrier made of a structurable material with at least one continues opening which is closed by a porous membrane, characterized in that the porous membrane protrudes from the surface of the component surrounding the continuous opening. In some embodiments, the component further comprises a carrier substrate, wherein a side of the carrier substrate which faces the component and the opposite side of the component preferably form a fluid channel, wherein the at least one continuous opening of the carrier preferably communicates on its open side with the fluid channel. The component according to the invention is suitable for the installation and electrochemical measuring of transmembrane proteins, preferably in lipid bilayers. The invention also proposes different methods for producing the component.Type: ApplicationFiled: October 21, 2015Publication date: February 8, 2018Inventors: Thomas LISEC, Eric NEBLING, Stefan KUBICK, Steffen RUPP
