Abstract: During the production of consumable liquids such as milk, soup, and juice, the liquid consumable may be transferred from one location to another location through a fluid conduit. For example, a consumable liquid may be transferred from a storage tank to another destination through piping. At the end of the process, the piping may be purged with a flushing fluid to push the liquid consumable remaining in the piping to the end destination, thus preventing the volume of liquid remaining in the piping from being wasted. To control the flushing processing, fluid flowing through the piping may be fluorometrically analyzed to determine a concentration of product in the fluid. The flushing liquid can then be controlled based on the determined concentration. For example, the supply of flushing liquid may be terminated when the concentration of product falls below a threshold, indicating the flushing liquid is diluting the liquid consumable.

Abstract: In situ optical analysis of bacterial endospores can be inhibited when the endospores are present within an optically active carrier medium. To help isolate the endospores from the carrier medium, in some examples, the carrier medium is passed through a hydrophobic material that captures the endospores via hydrophobic attraction. Subsequently, a germination fluid and lanthanide source, such as terbium, can be added to the bacterial endospores captured on the hydrophobic material to form a lanthanide-dipicolinic acid complex in the germination fluid. The germination fluid can then be optically analyzed by measuring the fluorometric response of the lanthanide-dipicolinic acid complex to determine a concentration of the bacterial endospores in the carrier medium.

Abstract: A chemical sensor may include an electrode array for electrically interfacing with a fluid sample. The sensor can apply an electrical potential to the sample in order to effect a current flow within the sample. The sensor can measure the resulting current through the sample and determine characteristics about the fluid sample from the current measurement. In one mode of operation of the sensor, the applied electrical potential can be controlled to cause desired electrochemical reactions, such as oxidation or reduction, to occur within the sample to determine the concentration of the oxidized or reduced sample constituent. In another mode of operation, the applied electrical potential causes a current to flow simply due to the conductivity of the sample. In various embodiments, the sensor comprises a controller and a switch for switching between various modes of operation and applying appropriate electric potentials to the sample.

Abstract: An optical sensor may include multiple optical emitters configured to emit light into a fluid sample via an optical pathway. Light from the emitters can cause fluorescence from the sample and/or scatter off of the sample. Scattered and fluoresced light can be received by an optical detector in the sensor via the optical pathway, and used to determine at least one characteristic of the fluid sample. A second optical detector can provide reference measurements of the amount of light emitted to the sample. In one example, the optical detector can detect scattered and fluoresced light simultaneously. In another example, light is emitted and detected alternatingly. The sensor can be part of a system that includes one or more controllers configured to control the emitting and detecting of light to and from the fluid sample. The controller can use detected light to determine at least one characteristic of the fluid sample.
