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.
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.
Workplace with Polarograph on the left. A Polarograph is a chemical analysis instrument used to record automatic voltage-intensity curves.. The Polarograph uses an electrolytic cell consisting of an electrode or microelectrode small area, generally of the mercury drop type, which is a very fine capillary tube through which mercury flows slowly, which comes in the form of small droplets, which ...
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 .

Apple is offering a free AppleTV+ trial from January 3 to January 5.. AppleTV+ is known for original content like "Ted Lasso" and "The Morning Show." It's reportedly cutting back on spending for ...
Voltammetry is the study of current as a function of applied potential. Voltammetric methods involve electrochemical cells, and investigate the reactions occurring at electrode/electrolyte interfaces. [4]
