Abstract: Methods and sensing instruments are provided which perform automated electrochemical sensing and determination of metals in a liquid sample, such as drinking water or waste water. With use of microelectrode arrays, concentrations of metal are determined through a double potential step variation on anodic stripping coulometry, and the ability to generate these results provides for compact sensor networks that can be remotely deployed for determination of metals in samples, for real-time, decentralized sample monitoring.

Abstract: Present embodiments provide an energy-efficient separator having at least two chambers fluidically isolated by a gas permeable membrane for the removal of dissolved gases from a sample which, in some aspects, enables cost-effective monitoring of liquid samples to be performed remotely and automatically, and in other aspects is suited for various other applications where removal and/or regulation of gases in a sample are desirable.
