fluoride probe short life

Proposed steps

• Clean the probe with deionized water that has the pH lowered to 3 using HCl. This would clean any coagulant nanoparticles from the probe in case those nanoparticles are interfering with the measurements
• call the fluoride probe vender to see what cleaning steps they suggest
• See Fluoride probe manual for possible suggestions for measurements/care/cleaning
• investigate options at VWR. search for Fluoride electrode
• It looks like we will have to pay something between $600 and $1000. I am concerned that given how we use the probe that these expensive probes won't last any longer... So Ideally we figure out what is required to care for a probe so that it lasts longer!

Ok, we'll try that and update you as we go!
