Witrynaimpurities are compared, there is limited indication of interaction between impurities. For example, copper improves the efficiency of Ti- and V-doped cells, although the effect is small. Apparently, Cu diffuses to and combines with the second transition metal to reduce its electrical activity. Precipitated impurities have little or no effect ... WitrynaDisregard limit: inject a solution of the substance to be examined at a concentration corresponding to the disregard limit (e.g. 0.05% of the concentration of the test solution) and note the area of the principal peak. a) Disregard the peaks in the chromatogram obtained with the test solution having an area lower than or equal to this peak area.
