Testing of water samples for physiochemical parameters:
Mains/ wells: Ammonia, chloride, fluoride, hardness, TON, nitrite, nitrate, sulphate (wells), pH, conductivity, turbidity, Iron and Manganese (wells)
Comprehensive: Alkalinity, ammonia, chloride, fluoride, hardness, TON, nitrite, nitrate, sulphate, pH, conductivity, TDS, turbidity, arsenic, calcium, copper, iron, potassium, magnesium, manganese, sodium, lead, selenium, zinc
Taking a water sample
The analytical result is only as good as the sample submitted for analysis. Collecting a representative sample is the first step of the analytical procedure.
Clean tap thoroughly, including the inlet with a flame or disinfectant wipe.
Turn on the tap and allow water to run for a minimum of 2 minutes.
Take the cap off the sterile bottle and immediately fill the container.
Replace the bottle cap as soon as the bottle is full (leaving a small headspace) and record the site and date of sampling.
Deliver to the IEC as soon as possible.
Maintain the water samples at 1-5°C if storing overnight.
