Chemical analysis moisture analyzers mainly include Coulomb moisture meters, dew point moisture meters, and Karl Fischer moisture analyzers.
(1) The dew point moisture analyzer is easy to operate, the instrument is not complicated, and the measured results are generally satisfactory. It is often used for the determination of trace moisture in permanent gas. However, this method interferes more. Some cold-changeable gases, especially at higher concentrations, interfere with condensation than water vapor.
(2) Coulomb moisture analyzer is commonly used to determine the moisture content in gas. This method is easy to operate, quick to respond, and especially suitable for the determination of trace moisture in gases. If you use ordinary chemical methods, it is very difficult. However, electrolytic methods are not suitable for the determination of alkaline substances or conjugated diolefins.
(3) Karl Fischer's method for measuring the volume of water in 1935. The Fischer method is the most specific and accurate method for determining water in various types of chemical methods. Although it is a classical method, it has been improved in recent years, improving accuracy and expanding the measurement range. It has been listed as a standard method for determination of moisture in many substances.
Karl Fischer is a classical method, also known as trace moisture analyzer, which is mainly used for the detection of samples with low moisture content. After improvements in recent years, it has greatly improved the accuracy and expanded the measurement range.
