A flow-through cell comprising a substrate defining a channel 4 having an inlet 6 and an outlet 8, at least a portion of the substrate being light-permeable to allow particles within at least a portion of the channel between the inlet and the outlet to be optically detected ( by means camera 24 and lens 26) through the substrate, wherein the flow-through cell comprises liquid-permeable particle retaining means 10 located downstream of the portion of the channel where particles can be optically detected The flow-through cell is particularly applicable to the detection of micro-organisms In drinking water. The device may comprise a number of channels wherein wicking means extends between the inlet and outlet, or where the outlets of each channel open into a single aperture. A detector is provided that may scan across the channels. |
