PLANAR BICARBONATE SENSOR

摘要

A planar bicarbonate sensor has been discovered that has a dried residue internal electrolyte layer comprising a bicarbonate source and a halide salt of potassium, lithium, or sodium. The flow-through sensor is capable of providing bicarbonate level of a liquid sample, and when coupled with a pH sensor, may be used to determine the partial carbon dioxide level in the sample. The sensor provides many commercially desirable characteristics including an adequate lifetime, good response time, and good stability upon first usage.
