![]() ![]() ![]() An Amicon CFF system showed higher (2–12 ×) colloidal concentrations for Cu and Ni compared to Filtron and Osmonics systems all CFF systems showed similar Cd, Cu and Ni mass-balance results. Differences in mass balance between these studies may be related, in part, to removal of sub-μm particles and associated trace metals during prefiltration. ![]() Mass-balance results averaged 93 ± 6% (Cd), 81 ± 19% (Cu), and 99 ± 18% (Ni) for the intercomparison experiment and 56 ± 17% (Cd), 119 ± 38% (Cu), and 91 ± 6% (Ni) for the Gulf of Maine samples. Size-fractionated samples were collected as part of a CFF intercomparison experiment (Buesseler et al., 1996-this issue) and in the Gulf of Maine. (E) Household Products' evaluations of Filterator X water filters have been consistently negative.A 1-kDa (1 kDa = 1000 daltons) Osmonics spiral-wound cross-flow filtration (CFF) membrane has been evaluated for sampling Cd, Cu and Ni in 1-kDa fractions of prefiltered seawater. (D) Very few people who own a Filterator X read Household Products on a consistent basis.:- out of scope our goal is undermine the company spoke person's conclusion (C) People whose household water contains chemical contaminants are more likely than other people to buy a Filterator X water filter.:-What the people buying or not buying is not impacting the conclusion. :- Correct of Most of Filterator X owner have no way to determine the how the product is removing chemical contaminant they are unable to evaluate it, and may be they are satisfy with other feature of the product (B) Most Filterator X owners have no way to determine how effectively the product removes chemical contaminants from water. (A) Household Products did not evaluate whether the Filterator X water filter significantly improved the taste of drinking water.:- taste is out of scope, Household Products magazine claim- Filterator X water filter does not remove chemical contaminants in significant amounts.Ĭompany spokesperson:- This attack on the quality of our product is undermined by the experience of the millions of Filterator X owners who are satisfied with the product's performance. (E) Household Products' evaluations of Filterator X water filters have been consistently negative.-> This is questioning the Premise, which can never happen, we can't challenge Premise. (D) Very few people who own a Filterator X read Household Products on a consistent basis. (C) People whose household water contains chemical contaminants are more likely than other people to buy a Filterator X water filter.-> We are not able to find the fault in Filterator X owner's satisfaction so discarded. (B) Most Filterator X owners have no way to determine how effectively the product removes chemical contaminants from water.-> Correct this is the actual reason, since they don't know how effectively the product removes chemical contaminants from water, they are satisfied. (A) Household Products did not evaluate whether the Filterator X water filter significantly improved the taste of drinking water.-> Taste is new variable so discarded. This can only happen if we find some fault in the Filterator X owner's satisfaction. Now we have to weaken the argument of spokesperson. Which one of the following, if true, most seriously undermines the company spokesperson's argument? So S1 tells that Filterator X does not remove chemical contaminants in significant amounts while S2 tells that owners are satisfied with the performance. Sentence 2: This is an attack on the quality of our product is undermined by the experience of the millions of Filterator X owners who are satisfied with the product's performance. Sentence 1 : Household Products magazine claims that our Filterator X water filter does not remove chemical contaminants in significant amounts This attack on the quality of our product is undermined by the experience of the millions of Filterator X owners who are satisfied with the product's performance. Company spokesperson: Household Products magazine claims that our Filterator X water filter does not remove chemical contaminants in significant amounts. ![]()
