    摘要： A method of measuring ultra-low concentration of a target analyte in a host fluid includes placing a droplet by a micropipette having an ejection tip, positioned by a micro-positioner, configured to position the ejection tip atop a first electrode in electrochemical contact with an electrolyte disposed in a first vessel, iteratively applying a potential to the first electrode and measure electrical current between the first electrode and a second electrode in electrochemical contact with the electrolyte, obtaining current vs. voltage curves for each voltameter iteration, identifying redox or oxidation peaks for each voltameter iteration, determining initial target analyte concentration based on the identified redox or oxidation peaks.

    摘要： A system for detecting the formation of a crack in a metal joint includes an electrochemical electrical current detection device. Carrier material surrounds the metal joint, at least partially, with conductive media having electrolyte therein. An auxiliary electrode is in electrical contact with the carrier material. The placement of the auxiliary electrode in electrical contact with carrier material forms a passive layer on the metal joint. The formation of a crack in the metal joint ruptures the passive layer to generate a current for detection by the electrochemical electrical current detection device.

    摘要： It is intended to provide, for example, a liquid sample measurement device capable of measuring the amounts of components of a liquid with a high accuracy. A first voltage is applied to an electrode pair 21, 22, which composes a biosensor 1, to obtain a first response value, a second voltage is applied to an electrode pair 23, 24, which composes the biosensor 1, to obtain a second response value, and a current that is generated when a third voltage is applied to an electrode pair 23, 27, which composes the biosensor 1, is detected to obtain a third response value. A liquid sample measurement device 6 uses the first response value, the second response value, and the third response value to obtain the concentration of glucose and the amount of blood cells of blood as well as the value equivalent to the temperature of the biosensor 1.
