Important Note. Lugols, the compound that is often used in these analyses, is very aggressive. It is best to keep the time that lugols spends in the chamber to a minimum and then it should be washed out promptly and thoroughly using normal laboratory soap solutions. Do not use heat in the analysis or drying process.
