✦ Synopsis

with a liquid membrane-based pH electrode, a relatively easy-to-manufacture modified Thomas electrode has been developed. The liquid membrane-based modified Thomas electrode can be manufactured without the special equipment (forge) and materials (glass) required to make the glass membrane pH microelectrode (L. R. Pucacco and N. W. Carter (1976) Anal. Biochem. 73, 501-5 12). The sensitivity (57.4 * 0.22 mV/pH unit), response time (20.0 + 2.67 s), and electrical resistance (3.48 + 0.67 X 10" ohm) of this electrode are similar to those of the glass-based version.
