Abstract
1,154,118. Electro-chemical analysis. INTERNATIONAL BUSINESS MACHINES CORP. May 20, 1968 [July 14, 1967], No.23868/68. Heading G1N. A pH meter has glass indicator and reference electrodes. A suitable pK sensitive glass comprises NaO, CaO and silica; a non-pH sensitive glass for the reference electrode comprises Boron oxide, CaO, and silica. Several electrode constructions are illustrated in Figs. 1 . . . 5 (not shown), e.g. Fig. 1 the electrodes may be glass tubes holding an intermediate electrolyte, Fig.2, a thin coating covering a platinum wire; Fig.3, a tubular alumina probe with openings in the side walls holding electrode areas; Fig.4, a hypodermic stainless steel needle covered in insulating material with outer electrode areas; Fig. 5 two tubes joined in series through which the sample flows, contact being made with the external surface by mercury cups. Reference is made to testing blood, cosmetics, and cheese.
