WitrynaAn impurity detector atomizes a liquid sample by injecting the sample into a chamber with a gas. In the chamber the liquid is heated, preferably by heating the gas prior to injection, to cause all the liquid to evaporate. The solid impurities contained in the liquid are thus entrained in the gas and carried to a detector region. The chamber is … 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 ...
