Carry out this procedure as directed then test the pre-concentrated sample as above (seenext page).
  • Page 258 Pre-Concentration Pre-concentration usesexactly 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 asrequired in order to concentrate the polyacrylate/polymer sufficiently for analysis.
