Abstract
1371438 Electro-chemical analysis INSTRUMENTATION LABORATORY Inc 19 May 1972 [21 May 1971] 23722/72 Heading G1N In an arrangement for INDICATING MEMBRANE LEAKAGE in an electro-chemical cell having a permeable membrane between the sample solution and the sensor probe, the voltage from the reference half-cell in the probe is used to monitor the membrane (instead of an external A.C. or D.C. supply as heretofore.) CELL CONSTRUCTION, Fig.1. A cell 10 is shown with two probes 16, 20 having respective membranes 32, 52, for the simultaneous measurement of pO 2 and pCO 2 . A stainless steel electrode 60 is provided at one end of the cell for the membrane monitoring circuits. The sample enters through a side port 12 and exits at end 14. As described the pO 2 sensor 16 has a Pt wire cathode 24 mounted in a glass tube 26 surrounded by an Ag/AgCl sleeve 28. The tip is covered by a polypropylene membrane 32. The pCO 2 sensor uses a combination glass electrode 40 (having an internal Ag/AgCl reference 44) and a co-operating external Ag/AgCl reference electrode 46. The MONITORING CIRCUIT Fig.2 for each sensor membrane is connected between the sensor reference electrode and the earthed stainless steel electrode 60, and comprises an operational amplifier 80 controlling a transistor pair 94, 96 to energise a warning lamp 74 when the membrane resistance falls below a predetermined value. In the case of the pO 2 sensor a bias for the reference electrode 28 is applied to the positive terminal of the operational amplifier.
