Abstract: Nephelometric measuring devices are described. The nephelometric measuring devices can be configured such that an amount of scattered light having different pathlengths impingent upon one or more scattered-light detectors from a beam propagating through a suspension can result in substantially equivalent sensitivity and in correlation between the scattered-light detectors' response and a turbidity value of the suspension. The response of the scattered-light detector(s) receiving scattered light at a nephelometric angle of 85-110° from a beam of light propagating through the suspension can be in accordance to an equation selected from a group of non-linear equations where: x/y=aoxn+ ++a2x2+aix+ao; where “n” is an integer greater than 0; “x” is equal to the turbidity value of the suspension; “y” is equal to the response of the scattered-light detector; and “an” are calibration coefficients.

Abstract: Embodiments of the present invention include a backscatter reductant anamorphic beam sampler. The beam sampler can be implemented to measure a power of a reference beam generated by an electromagnetic radiation source in proportion to a power of a working beam. The beam sampler can provide astigmatic correction to a divergence of the working beam along one axis orthogonal to a direction of propagation. The beam sampler can further be implemented to prevent backscatter reentrant radiation from impinging upon a photodetector of the beam sampler resulting in a reduction of error and instability in an assay of the working beam.

Abstract: Embodiments of the present invention include a device for removing energy from a beam of electromagnetic radiation. Typically, the device can be operatively coupled to a turbidity measuring device to remove energy generated by the turbidity measuring device. The device can include a block of material having one of a plurality of different shapes coated in an energy absorbing material. Generally, the device can include an angled or rounded energy absorbing surface where the beam of electromagnetic radiation can be directed. The angled or rounded energy absorbing surface can be configured to deflect a portion of the beam of electromagnetic radiation to a second energy absorbing surface.

The measurement module can removably couple to the fluidic module and be implemented to measure a turbidity of a liquid passing through the fluidic module.

In one instance, the deaerator can be implemented to separate entrained air and/or other gases from a continuous flow of liquid by means of nucleation before the liquid is assayed.

Abstract: A nephelometric process turbidimeter for measuring a turbidity of a liquid sample includes a transparent sample vial which comprises a sample vial lateral inner surface. A vial head comprises a vial head lateral inner surface. The vial head and the sample vial together define a sample volume of a liquid sample having a shape of a cylinder. A sample inlet opening is arranged at the vial head and comprises an inlet opening axis. A sample outlet opening is arranged at the cylindrical vial head lateral inner surface to be axially closer to the sample vial than to the sample outlet opening. The inlet opening axis is inclined with respect to an inlet cross plane with an inclination angle of 10° to 80°, and is angled with respect to a radius line from a middle of the cylinder to the sample inlet opening with a tangency angle of more than 15°.
