PCT No. PCT/GB94/01994 Sec. 371 Date Apr. 23, 1996 Sec. 102(e) Date Apr. 23, 1996 PCT Filed Sep. 13, 1994 PCT Pub. No. WO95/08112 PCT Pub. Date Mar. 23, 1995A multi-sensor flow-through system which mitigates or at least overcomes any cross field effects between different sampling conduits comprising a plurality of flow-through sample cells (2), wherein each sample cell (2) is provided in an independent and isolated sample channel (16a, 16b. . . ), whereby fluid flowing within each channel (16a, 16b, . . . ) is isolated from fluid flowing in neighboring channels (16a, 16b, . . . ). In one embodiment of the multi-sensor system, each sensor cell (2) operates as an autonomous and independent unit isolated from all other units. Ideally, each of the sample channels (16a, 16b, . . . ) are also independent and isolated from other sample channels (16a, 16b. . . ). The multi-sensor system can additionally have the exit end of the channels (16a, 16b, . . . ) feed into a well in such a way that free space is provided between the ends of the channels and the uppermost surface of fluid in the well. A further improvement is the use of a single inlet conduit (15) which passes through at least one reagent chamber (4, 5, 6), whereby at least reagent is added to the sample before the reagent supplemented sample passes into the plurality of sampling channels (16a, 16b, . . . ). |
