Page 22 1.1 Methods The precision of Lovibond Reagent Systems (tablets, powder packs and tube tests) is identical ® to the precision specified in standards literature such as American Standards (AWWA), ISO etc. Most of the data referred to in these standard methods relates to Standard Solutions. Therefore they are not readily applicable to drinking-, boiler- or waste-water, since various interferences can have a major influence on the accuracy of the method.

Colour, true and apparent (APHA Platinum-Cobalt Standard Method) 0 – 500 Pt-Co units Sample preparation (Note 4): Step A Filter approx. 50 ml deionised water through a membrane filter with a pore width of 0.45 μm. Discard the filtrate. Filter another 50 ml deionised water and keep it for zeroing.
Page 105 Notes: 1. This colour scale was originally developed by A. Hazen as a visual comparison scale. It is therefore necessary to ascertain whether the extinction maximum of the water sample is in the range from 420 to 470 nm, as this method is only suitable for water samples with yellowish to yellowish-brown coloration.

Page 255 Notes: 1. Fill the vial with drops of the same size by holding the bottle vertically and squeeze slowly. 2. If little or no turbidity is present at correct dose concentrations, the sample will need a pre-concentration step in order to detect this level of polyacrylate/polymer. Carry out this procedure as directed then test the pre-concentrated sample as above (see next page).
Page 256 Pre-Concentration Pre-concentration uses exactly the same procedure as interference removal, except a greater volume of sample is used in step 1, instead of deionised/tap water. For calculation of the original sample concentration a concentration factor should be considered: If a 50 ml sample is used the concentration factor is 20/50 = 0.4 If a 100 ml sample is used the concentration factor is 20/100 = 0.2 This can be extended as required in order to concentrate the polyacrylate/polymer sufficiently for analysis.
