ABSTRACT:
A continuous sample detector has a cell assembly with a spaced pair of sample cells. Each of these cells is mounted in a sample chamber and each is adapted to conduct a continuous sample flow. These sample cells are connected through a plurality of sample lines. The continuous sample detector also includes a sensor that is mounted and arranged proximate the cell assembly. Relative motion between the sensor and the cell assembly will enable the sensor to alternately detect radiation predominantly from a selected one of the cells. The sensor and the cells are positioned within the common housing to detect radiation with the sensor from predominantly a first one of the sample cells. The sample flow may at that time pass through the first one of the sample cells. The relative position of the sensor and the sample cells may then be changed within the common housing to detect radiation with the sensor from predominantly a second one of the sample cells. The sample flow may at this time pass through the second one of the sample cells, without disconnecting any of the plurality of sample lines.
