Abstract
An optical signal source is positioned at a first side of the flow cell or the flow-line bypass. The optical signal source is capable of emitting an optical signal through the first side of the flow cell or the flow-line bypass. A first optical detector is positioned at a second side of the flow cell. The second side is opposite the first side. The first optical detector is capable of detecting a transmitted-light intensity of the optical signal transmitted through the second side of the flow cell or the flow-line bypass. A second optical detector is positioned at a third side of the flow cell. The third side is different than the first side and the second side. The second optical detector is capable of detecting a scattered-light intensity of a scattered optical signal transmitted through the third side of the flow cell or the flow-line bypass.
