coulometric การใช้

• Coulometric titrations use a constant moles of the unknown species in solution.
• The Karl Fischer reaction uses a coulometric titration to determine the amount of water in a sample.
• The results obtained by this coulometric method are similar to those achieved by other chemical and metallurgic techniques.
• The coulometric method can allow for variable test times, whereas the test time on a meter using the amperometric method is always fixed.
• The coulometric method is a technique where the total amount of charge generated by the glucose oxidation reaction is measured over a period of time.
• There are two basic categories of coulometric techniques . " Potentiostatic coulometry " involves holding the electric potential constant during the reaction using a potentiostat.
• The other, called " coulometric titration " or " amperostatic coulometry ", keeps the current ( measured in amperes ) constant using an amperostat.
