Claim 9:
10. A method for measuring metal content of an aqueous solution, wherein the method is implemented via a portable assessment kit, the method comprising:
obtaining, in a sample container, a sample of the aqueous solution to be assessed, wherein the sample container comprises an opening at its first end for receiving the sample;
detachably attaching a disc holder to the opening of the sample container, via a first part of the disc holder having a first end of the disc holder, wherein the disc holder has the first end and a second end opposite to the first end;
arranging a permeable pre-concentration disc between a second part of the disc holder and a third part of the disc holder in a manner that a first side of the pre-concentration disc is facing the second part of the disc holder and a second side of the pre-concentration disc is facing the third part of the disc holder, wherein the pre-concentration disc having the first side and the second side opposite to the first side is arrangeable in the disc holder;
pumping the sample of the aqueous solution through the opening of the sample container to the first side of the permeable pre-concentration disc and through the pre-concentration disc; and
measuring, using a measurement device, amount of metals in the pre-concentration disc, the measurement device being arrangeable in connection with the disc holder in such a manner that the first side of the pre-concentration disc is facing the measurement device.
