Fluoride in Urine
Fluoride in urine is measured using a known Addition method. The QP459 ION meter has this method as standard and will display results directly in ppm Fluoride.
Quick Ion Analysis
To measure the concentration of any Ion in samples is traditionally quite expensive as you need to purchase an ION meter. However if you are looking for a quick, easy and cost effective method this excel calculator is for you.
Sulphide Measurement
Sulphide is unstable and needs to be fixed before analysis. Both standards and samples need to be protected from oxidisation before analysis can be performed.
Ionic Strength Adjustment Buffers (ISAB)
To make sure the ionic strength is similar in all standards and samples add a known volume of ISAB to a known volume of each standard and sample.
