摘要： Described herein are methods and devices of detecting a particulate analyte in a sample solution, using an electrochemical cell having an anodic compartment and a cathodic compartment, wherein the anodic and cathodic compartments are separated by a semi-permeable membrane. The sample solution is acidified by applying a positive current to the anodic compartment and maintaining the positive current to permit anions to flow from the cathodic compartment to the anodic compartment through the semi-permeable membrane. The analyte is deposited on an electrode disposed in the anodic compartment by applying a negative current. The deposited analyte is stripped from the electrode and an electrochemical voltammogram is generated by measuring the current as the analyte is stripped from the electrodes. The voltammogram is used to determine the concentration of the analytes in the sample solution based on the generated electrochemical voltammogram.

摘要： There is provided a biosensor for detecting water contaminants. The biosensor has a microbial fuel cell compartment, having (i) at least one opening to allow water into and out of the microbial fuel cell compartment, (ii) an anode comprising electroactive microorganisms, and (iii) a cathode. The anode is electrically and physically separated from the cathode. The anode is anaerobic and comprises electroactive microorganisms. The cathode is aerobic. The biosensor has a storage compartment housing a biodegradable carbon source to supply the biodegradable carbon source to the electroactive microorganisms; an electric impedance load; an electric switch forming an intermittent connection between the microbial fuel cell compartment and the electric impedance load; an electric sensor; and a control system coupled to the electric switch and the electric sensor, receiving a measurement from the electric sensor, and outputting an indication signaling the presence or absence of the water contaminants based on the measurement.

摘要： An apparatus and method of adjusting a plating solution are described. Suppressor is added to the plating solution until a comparison to reference data of an RDE potential taken at a first time during a constant current experiment indicates a threshold suppressor concentration is present. The amount of suppressor added to reach the threshold suppressor concentration is used to determine suppressor concentration of the solution. Another amount of suppressor is added to a new plating solution so that the new plating solution has a specific suppressor concentration. The RDE potential or slope of RDE potential change of the new plating concentration with the specific suppressor concentration taken at a second time during another constant current experiment is compared with the reference data to determine the leveler concentration. The suppressor and leveler concentrations of the original plating solution are adjusted before a semiconductor substrate is plated.
