MA-2A Coulometric moisture analyzer electrolyte safe use method
MA-2A electrolyte (Karl Fischer reagent) is used for the determination of moisture in the Coulometric electricity micro-moisture analyzer and is an important part of the instrument. The use of the instrument and electrolyte is detailed in the instruction manual of the trace moisture analyzer. Because the electrolyte has certain odor and toxicity, special attention is required. The specific precautions are as follows:
1. The main components of the electrolyte are iodine, methanol, sulfur dioxide, ethylene glycol (including pyridine electrolyte containing pyridine) and other components, should be stored in a dry place in the dark, the storage time is half a year.
2. The electrolyte has certain toxicity, the smell is unpleasant and flammable. Care must be taken when replacing the electrolyte. The reagent should be loaded or replaced on a well-ventilated test bench.
3, the electrolyte is very absorbent, the electrolyte must be in a dry environment, the utensils used must be dry, the electrolytic cell accessories should be placed on the dry filter paper.
4. Care must be taken when replacing the electrolyte. Do not touch the reagents in the mouth or by hand. If it is in contact with the reagent, rinse thoroughly with water. Due to the high taste of the reagents and the toxic components, the ventilation in the laboratory is good or in a fume hood.
5, the electrolyte is stored in a well ventilated, ambient temperature 5 ~ 25 ° C, relative humidity is not more than 75%, if the electrolyte is exposed to direct sunlight or placed at high temperatures, then sulfur dioxide and iodine will be from pyridine Released and failed.
