• Nitrates occur in most ground and surface waters in concentrations of up to 20 mg/l. • In addition to mere geological influences nitrate concentrations can also increase from agricultural sources (fertilisers). • The VISOCOLOR® test kits are intended for the determination of nitrate in surface and drinking water and in industrial waste waters which do not contain high concentrations of interfering ions.
