Barringer (surface water) Chemtrix/Fisher ISE (F)

Barringer, surface water; ion-selective electrode (fluorine), mixed with total ionic strength adjustment buffer solution and measured with a Chemtrix/Fisher Accumet meter using an Orion fluoride electrode

General Methodology:

Fluoride was determined using a specific ion electrode.  An aliquot of the sample was mixed with an equal volume of a TISAB (Total ionic strength adjustment buffer) solution.  The fluoride was measured initially with a Chemtrix and subsequently with a Fisher Accumet expanded scale meter using an Orion fluoride electrode.
