The present invention is one that intends to achieve improvements in both analysis efficiency and analysis accuracy without difficulty, and a biological substance analysis device that analyzes light derived from a biological substance in a sample, and the biological substance analysis device includes: a holder that holds multiple containers containing the sample; a photodetector that is fixed at a predetermined position; a holder driving mechanism that moves the holder to position each of the containers held in the holder at a detection position by the photodetector in sequence; and a light shielding mechanism that, while guiding light emitted from the sample in a container at the detection position to the photodetector, prevents light emitted from the sample in the other containers from being guided to the photodetector.

Parameters of an alcoholic or non-alcoholic beverage can be determined through spectroscopic methods. In on example, the method includes obtaining a beverage sample and obtaining spectrographic data from the beverage. The spectroscopic data may be processed by a remote lab to determine a value range of the one or more beverage parameters, and a value of the one or more beverage parameters. The one or more beverage parameters may include one or more of beverage color, bitterness, Free Amino Nitrogen (FAN), yeast count and yeast viability.

Apparatuses and methods of optically analyzing fluid within a pipette are described herein. In an embodiment, an optical reader subassembly includes a housing including an internal area, a container configured to hold a fluid sample at a sample position in a light tight manner within the internal area of the housing, a light source configured to project light onto the fluid sample within the container, and an optical sensor configured to move between different sensor positions while the fluid sample remains stationary at the sample position, the different sensor positions including at least two of: (i) a first sensor position for taking a luminescence reading of the fluid sample; (ii) a second sensor position for taking a dark current or other background measurement; and (iii) a third sensor position for taking a fluorescence reading of the fluid sample.

Combine harvesters are provided for use in harvesting seed corn from corn plants in fields. In connection therewith, a method for producing such seed corn from the corn plants, for use in growing subsequent corn plants, includes measuring a moisture content of corn kernels on ears of the corn plants in the field and removing, by one of the combine harvesters, the ears of corn from the corn plants when the moisture content satisfies a threshold moisture content. The method then includes separating the corn kernels from cobs of the ears of corn onboard the combine harvester and collecting the separated corn kernels for use as seed corn, whereby one or more subsequent corn plants can be grown from the collected corn kernels.

Various embodiments of a light detection device and a method of using such device are disclosed. In one or more embodiments, the light detection device can include a housing including a top surface and a bottom surface, where the housing extends along a housing axis between the top surface and the bottom surface; and a support member connected to the housing and adapted to be selectively moved from a closed position to an open position. The support member is further adapted to maintain the light detection device in an upright position when the bottom surface and the support member are in contact with a working surface and the support member is in the open position.

Various embodiments of a light detection device and a method of using the device are disclosed. In one or more embodiments, the light detection device can include a housing that extends along a housing axis between top and bottom surfaces. The device can also include a port that is adapted to receive a sample, and a door connected to the housing. The door can include an actuator portion adapted to selectively move the door between a closed position and an open position, and a cover portion connected to the actuator portion and adapted to close the port when the door is in the closed position and open the port when the door is in the open position to allow external access to the port.
