1. According to the standard, we know that fluoride in fixed source exhaust gas can exist in two states: particulate fluoride and gaseous fluoride. When both coexist, both constant velocity sampling and absorption bottle sampling need to be used simultaneously. When there is only gaseous fluorine, sampling with an absorption bottle is sufficient. So on-site sampling personnel need to analyze the presence of fluoride in the exhaust gas in advance based on the production process and raw materials, and make corresponding preparations.
