A Karl Fischer titrator. In analytical chemistry, Karl Fischer titration is a classic titration method that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. [1] [2] Today, the titration is done with an automated Karl Fischer titrator.
Karl Fischer (24 March 1901 – 16 April 1958) was a German chemist. [1] In 1935 he published a method to determine trace amounts of water in samples. [2] This method is now called Karl Fischer titration and was originally performed manually but has been automated. It remains the primary method of water content determination used worldwide by ...
According to The Associated Press, The Los Angeles Department of Water and Power was pumping from aqueducts and groundwater into the system, but "demand was so high that it wasn't enough to refill ...
If the volatile content of the solid is primarily water, the loss on drying technique gives a good measure of moisture content. [5] Because the manual laboratory method is relatively slow, automated moisture analysers have been developed that can reduce the time necessary for a test from a couple of hours to just a few minutes.
Karl Fischer Coulometer Auto Titrator. The Karl Fischer reaction uses a coulometric titration to determine the amount of water in a sample. It can determine concentrations of water on the order of milligrams per liter. It is used to find the amount of water in substances such as butter, sugar, cheese, paper, and petroleum.
Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood. Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials' porosity at saturation.
The former head of the Panoche Water District stole more than $25 million in water from a federal canal from 1992 to 2015, prosecutors say. Former Central California water manager stole $25 ...
The Mulholland Dam is a Los Angeles Department of Water and Power dam located in the Hollywood Hills of Los Angeles, California, east of the Hollywood Freeway.Designed with a storage capacity of 7,900 acre⋅ft (9,700,000 m 3) of water at a maximum depth of 183 feet (56 m), the dam forms the Hollywood Reservoir, which collects water from various aqueducts and impounds the creek of Weid Canyon.
