| Overview | Karl-Fischer reagent is a reagent for the determination of trace moisture in organic matter, so it is also called water reagent, also called Karfeldt reagent. The initial water reagent is mainly prepared by iodine, sulfur dioxide, methanol and pyridine in a certain proportion. This reagent has foul smell and great toxicity, poor stability, shelf life within three months, and is not suitable for the determination of aldehydes and ketones, which brings inconvenience to users in storage and use. With the advent of the full-automatic Kar's moisture meter, the requirements for Kar's reagent have also increased accordingly. |
| formula principle | the formula principle of the new electrolyte is: ① mix with two solvents. to achieve complementarity. ②Use two weak acids to provide the required two anion groups. (3) Add alkali, such as organic amine, to adjust the pH value of electrolyte and flash voltage. change its resistivity. (4) Additives that improve the characteristics of the electrolyte, such as phosphoric acid or its salt that prevents the hydration of the aluminum oxide film, dinitrobenzene that absorbs hydrogen, etc., and ethylene oxide that increases the flash voltage of the electrolyte. |
