Aluminium testing
There is no Ion Selective Electrode for Aluminium however due to the strong reaction with Fluoride in solution an indirect method is possible using a Fluoride ISE and some prepared reagents.
EDT Electrodes and Mettler Toledo Meters
Combination ISE’s and pH electrodes are compatible with all meters except for the multiparameter instruments.
Methods of Analysis by ISE
Unlike a pH electrode an ISE is not just dipped into a solution and a direct readout obtained.
Sulphide ISE Reagent Prep
Sodium Sulphide standard solutions can be prepared from reagent grade Sodium Sulphide Hydrate Na₂S.9H₂O. It is advised that all Sulphide solution preparation be performed in a fume hood to avoid breathing Noxious fumes.
Bromide in Water
A method for the measurement of Bromide in ground, drinking and waste waters from 0.5 ppm to 1000 ppm.
EDT Electrodes and Hanna Meters
There are many pH and ION meters in laboratories all over the world. Many years ago some manufacturers had their own style of connector which prevented competitors from substituting their electrodes with their own.
Determination of Calcium in Beer
The concentration of Calcium in Beer is determined directly by using the technique of standard addition
Mooring
Mooring your boat in a Marina can be a lottery. Whilst most are safe, reliable and offer a safe haven for your boat there are reasons to take care in checking where you are leaving your valuable craft.
Determination of Potassium in Soil
Immerse the electrode in each of the standards in increasing concentration steps in the calibration mode of the Ion Meter.
Silver Spoons and Boat Hull Testing
Hull potential requires a Silver/Silver Chloride (Ag/AgCl) reference electrode. This is correct, the key thing here is not that it contains Silver but that is a reference electrode.
