Scope
Main technical content: This document specifies the determination methods for nitrate and fluoride in brine. This document is applicable to the determination of nitrate and fluoride in brine. When the sample injection volume is 100 uL, the detection limit of nitrate is 0.040 mg/L, the lower limit of nitrate determination is 0.16 mg/L, and the upper limit of nitrate determination is 5000 mg/L. The detection limit of fluoride is 0.040 mg/L, and the lower limit of fluoride determination is 0.16 mg/L. The upper limit of fluoride determination is 200 mg/L.
