  • Method approved by ASTM for water, drinking water, wastewater and seawater brines and it is approved by EPA, Standard Methods and AOAC for feeds
  • Range saturated to 0.02 ppm
  • Requires 4215F10 reference electrode. Uses 4215F20 fill solution

  • Fluoride standard, 0.1000 M ±0.0005
  • Fluoride standard, 100 ppm ±0.5 ppm
  • 1 or 2 ppm Fluoride standard with TISAB buffer, for use without dilution

TISAB III Buffer Concentrate

  • For total ionic strength adjustment in fluoride analysis of drinking water
  • Contains CDTA to release fluoride complexed by iron or aluminum

Must be diluted 10:1 before use. Diluted buffer is then mixed 1:1 with standards and samples for adjustment of pH and increased ionic strength to compensate for differences among samples.

TISAB II Buffer

  • Similar to 4210F37, but not concentrated
  • Standards and samples are diluted 1:1 directly with the buffer
