SAMPLE TESTING APPARATUS AND METHOD

摘要

A test apparatus (12) and a method of testing a sample (30) are disclosed. The method comprises receiving a test sample (30) within a test chamber (14), the test chamber (14) containing two or more iron saturation elements (2) separated by a spacer (16); and filling the test chamber (14) with a test solution, the iron saturation elements (2) being arranged to saturate the test solution with iron. Each iron saturation element (2) is shaped such that it has a predetermined surface area such that the ratio of the volume of the test solution to the surface area of the iron saturation elements (2) and the test sample (30) exposed to the test solution can be calculated.
