A method for determining contents of sample liquids spectrometrically includes an empty-state measurement with no liquid present, to obtain an empty-state light intensity measurement I.sub.e. A liquid-blank measurement is then taken of a pure unmixed volume of said liquid component, to obtain a liquid-blank light intensity measurement I.sub.w. A sample measurement of the sample liquid is then taken to obtain a sample light intensity measurement I.sub.s. Using I.sub.e, I.sub.w, and I.sub.s, determination is made of a volume concentration of a liquid component [H2O] in the sample liquid, and a liquid-corrected light intensity measurement I.sub.wc. From I.sub.s, I.sub.wc and a known length of the light path, a volume concentration of alcohol [Alc] is calculated. From [H2O] and [Alc], a remnant volume concentration attributable to other constituents is determined, from which a carbohydrate concentration [Carb] is calculated using a predetermined carbohydrate coefficient. Provisions for turbidity determination and light scatter correction are included.

An optical density testing system includes a light source, a first light splitting device used to divide the light into at least two light paths, at least two second light splitting devices used for receiving the at least two paths of light from the first light splitting device, first light-passing holes provided corresponding to each of the at least two second light splitting devices, a first filter device detachably arranged at each of the first light-passing holes, a first diaphragm detachably installed on each of the first filter devices, and a light receiving device. The second light splitting device is used to transmit the light onto a product to be tested through the first filter device and the first diaphragm. The light receiving device is used to receive transmitted light formed after the light passes through the product to be tested.

A method is provided for the selective harvest of microLED devices from a carrier substrate. Defect regions are predetermined that include a plurality of adjacent defective microLED devices on a carrier substrate. A solvent-resistant binding material is formed overlying the predetermined defect regions and exposed adhesive is dissolved with an adhesive dissolving solvent. Non-defective microLED devices located outside the predetermined defect regions are separated from the carrier substrate while adhesive attachment is maintained between the microLED devices inside the predetermined defect regions and the carrier substrate. Methods are also provided for the dispersal of microLED devices on an emissive display panel by initially optically measuring a suspension of microLEDs to determine suspension homogeneity and calculate the number of microLEDs per unit volume. If the number of harvested microLED devices in the suspension is known, a calculation can be made of the number of microLED devices per unit of suspension volume.

An improved system, method and interface for automated rapid antimicrobial susceptibility testing (AST) is disclosed which includes, in one aspect, a carrier population station comprising a workstation having a graphic user interface (GUI). The GUI accepts information from a lab technologist, including information related to a scope of testing to be performed on a microorganism containing sample. The GUI controls intelligent assignment of microorganism containing samples to test panels in a manner that maximize utilization of the test carrier by grouping together samples of similar tests scopes and advantageously testing those samples using one multiplexed test panel. Customizing workflow in accordance with test scope to facilitate parallel processing of multiple samples advantageously reduces laboratory waste, decreases test latencies, increases AST system throughput and efficiency, and thus lowers the costs to the AST lab.

Methods for identifying and providing information about inhibiting growth of polymicrobial infections, including but not limited to providing statistics or information about the likelihood of success in inhibiting growth of a polymicrobial infection with particular compositions or therapeutic solutions. The methods herein feature detection and identification of organisms of the polymicrobial sample (e.g., polymicrobial infection), phenotypic pooled sensitivity tests for determining the susceptibility or resistance of the polymicrobial sample (e.g., polymicrobial infection) in the sample to an antibiotic or other therapeutic agent, and identification of resistance genes, e.g., genetic markers that may indicate resistance to a particular treatment. Together, the data can be applied against databases of antibiotic/therapeutic susceptibility or resistance for particular known polymicrobial samples (e.g., polymicrobial infections) in order to provide information related to the likelihood of success of one or more therapeutic solutions for the polymicrobial sample (e.g., polymicrobial infection).

A method for fast extracting an organic pollutant in a complex system is disclosed, which includes following steps. A surface-enhanced Raman scattering (SERS) spectrum of an organic pollutant is divided to obtain P wavelength sub-intervals with overlapping regions. The P wavelength sub-intervals are screened to obtain ω wavelength sub-intervals. The ω wavelength sub-intervals are screened to obtain a required wavelength sub-interval. The required wavelength sub-interval is screened to obtain a required wavelength subset. A method and a system for fast detecting an organic pollutant in a complex system are also disclosed.

A method, computer program product, and apparatus are provided for controlling components of a detection device. The device may detect turbidity of liquid with sensors such as a density sensor and/or nephelometric sensor. A light modulation pattern may reduce or eliminate interference in sensor readings. Readings may be performed during off cycles of an illumination light to reduce interference but to provide improved visibility of a tube. Dark and light sensor readings may be performed with an emitter respectively off or on to account for ambient light in subsequent readings. Readings from the density sensor and/or nephelometric sensor may be used to calculate McFarland values. The device may be zeroed based on an emitter level that results in a sensor reading satisfying a predetermined criterion.
