Buffers for fluoride electrode calibration in the low concentration range.
Thorium-buffered fluoride standards for calibration of fluoride electrodes at low fluoride concentration are described. Fluoride electrodes give Nernstian response down to very low fluoride levels, but the practical limit is set at about pF 6 by contamination from distilled water, reagents etc.
