We have a number of means of measuring chlorine dioxide as produced by the generator and as used in the process (the residual). These methods we briefly outline:

1. Aeita speciation titration using standard iodine / sodium thiosulphate chemistry. This procedure is used to determine the efficiency of the generator system.



2. Titration Kit - based on a) above, but developed as a field test kit which can measure low range chlorine dioxide (0-5ppm) or high range (0-100ppm). a) and b) have a number of interfering ions e.g. nitrite, manganese, iron.



3. Pallin Test Kit - this is the latest AWWA (American Water Works Association) approved test procedure that measures only chlorine dioxide and no other species including other oxidants. This test kit measures in 0.1ppm intervals at 1% accuracy.



4. Oxystix - a dipstick, like pH paper, which registers whether chlorine dioxide is present. This is a semi-quantitative procedure.
