Heyrovský's Polarograph. Polarography is an electrochemical voltammetric technique that employs (dropping or static) mercury drop as a working electrode. In its most simple form polarography can be used to determine concentrations of electroactive species in liquids by measuring their mass-transport limiting currents.
An electro-galvanic fuel cell is an electrochemical device which consumes a fuel to produce an electrical output by a chemical reaction. One form of electro-galvanic fuel cell based on the oxidation of lead is commonly used to measure the concentration of oxygen gas in underwater diving and medical breathing gases .
Leaded gasoline contaminates the oxygen sensors and catalytic converters. Most oxygen sensors are rated for some service life in the presence of leaded gasoline, but sensor life will be shortened to as little as 15,000 miles (24,000 km), depending on the lead concentration. Lead-damaged sensors typically have their tips discolored light rusty.
"Life's a climb. But the view is great." There are times when things seemingly go to plan, and there are other moments when nothing works out. During those instances, you might feel lost.
Clark's original cell was set up in a glass jar in a similar way to a gravity Daniell cell.The copper cathode was replaced by a pool of mercury at the bottom of the jar. . Above this was the mercurous sulfate paste and, above that, the zinc sulfate solu
Researchers from Mass General Brigham, a health care system in Boston, Massachusetts, shared with Fox News Digital some of the scientific developments and breakthroughs they expect to see in 2025.
Half of the teams in this year’s College Football Playoff are starting a transfer quarterback, including both teams in Friday night’s playoff opener between Indiana and Notre Dame.. The ...
Linear potential sweep. Voltammetry is a category of electroanalytical methods used in analytical chemistry and various industrial processes. In voltammetry, information about an analyte is obtained by measuring the current as the potential is varied.
