D No 1 but raises the DPD No 3 reading thus yielding a false high result for combined chlorine Unwary pool operators may add further shock dose at this point and this further raises the false total chlorine result Palintest s DPD Oxystop has been developed to prevent this problem The DPD Oxystop tablet should be added after the DPD No 1 Free Chlorine test result has been read and before the DPD No 3 tablet is added The tablet must be thoroughly crushed and mixed well into the solution and allowed a one minute stand before proceeding with the DPD No 3 tablet Thus Oxystop suppresses the response from MPS and allow accurate measurements of free and total chlorine on non chlorine shock dosed pool waters The DPD Oxystop tablet may also be used in exactly the same way with the DPD XF and DPD XT tablets To assess the level of non chlorine shock dose chemicals in the pool request supplementary instructions Phot 7 2 AUTO 29 pH Ionic strength temperature and other water factors will have an effect on pH readings This test has been calibrated for conditions most likely to be encountered in a typical swimming pool The colour range of the phenol red test is yellow through orange to red The formation of an intense purple coloration shows that the indicator has been affected by high chlorine or bromine residuals In such cases the result should be disregarded Alkalinity The Alkaphot test contains an organic acid titrant to

23. known colours To avoid subjective measurement between test samples and colour standards a photometer can be used for quantitative measurement of the amount of coloured light absorbed by a sample with reagents added in reference to an untreated sample blank White light is made up of many different wavelengths of visible light A photometer transmits a white light beam through an optical filter which permits only one particular band of wavelength of light to pass to the photodetector where it is measured The difference in the amount of coloured light transmitted by a colourless sample blank and the amount of coloured light transmitted by a coloured sample is a measurement of the amount of coloured light absorbed by the sample The use of filters improves the sensitivity of this process and choice of the correct optical filter and therefore the correct wavelength of light is important It is interesting to note that the filter that gives the most sensitive calibration for a test factor is the complementary colour of the test sample For example the chlorine test produces a pink colour proportional to the chlorine concentration in the sample the greater the chlorine concentration the darker the pink colour In this case a green filter gives the greatest sensitivity as a pinkish red solution absorbs mostly green light Palintest photometers calculate and then display the test results directly in milligrams per litre mg l of th
