| abstract | 1284952 Electro-chemical analysis HITACHI Ltd 14 May 1970 [16 May 1969] 23434/70 Heading G1N A flat pack detector cell for use in liquid chromotography comprises a flat measuring electrode 2 a pair of reference electrodes 4,4<SP>1</SP> and a pair of diaphragms 3, 3<SP>1</SP> disposed between the electrodes. The sample to be analysed e.g. a liquid containing dissolved oxygen is led to and away from the measuring electrode via tubes 5, 6 and an electrolyte such as NaCl is passed through tubes 7, 8, 9, 10, tubes 8, 9 being connected outside to pack by a tube, Fig.3 (not shown) so as to pass through reference electrodes 4,4<SP>1</SP>. The electrodes are in the form of platinum or silver wire netting or carbon cloth and the diaphragms 3, 3<SP>1</SP> disposed between resilient insulator plates 4A, 2A and 4<SP>1</SP> A<SP>1</SP>, 2A<SP>1</SP> are such as to permit particular ions in the electrolyte solution to pass therethrough but prevent the sample liquid and electrolysis products at the reference electrodes 4, 4<SP>1</SP> from passing therethrough. Electrodes 4, 4<SP>1</SP> are connected together and a constant potential is applied across electrodes 4, 4<SP>1</SP> and 2. Leads 11, 12 are connected to a coulometer, Fig.4 (not shown). In order to prevent clogging of tubes 5, 6 spaces are provided between the ends of the tubes and electrodes 2 Figs.5 and 6 (not shown). To prevent leakage at the diaphragms 3, 3<SP>1</SP> the latter are sandwiched between suitably impregnated cloth, Fig.7 (not shown). |
