摘要： Systems are provided for a modular multi-wavelength UV-VIS detector unit, such as an absorbance detector (e.g., spectrophotometer) included in a high-performance liquid chromatography system. In one example, a detector unit includes one or more light emitters and a sliding assembly configured to slidingly move a flow cell relative to the one or more light emitters, the one or more light emitters mounted on a floating rig to facilitate alignment between the one or more light emitters and the flow cell when the sliding assembly is in a closed position.

摘要： Systems and methods are provided for a UV-VIS spectrophotometer, such as a UV-VIS detector unit included in a high-performance liquid chromatography system. In one example, a system for the UV-VIS detector unit may include a first light source, a signal detector, a flow path positioned intermediate the first light source and the signal detector, a second light source, and a reference detector. The first light source, the signal detector, and the flow path may be aligned along a first axis, and the second light source and the reference detector may be aligned along a second axis, different than the first axis.

摘要： A system for irradiating a microplate may include a modular light engine with one or more light emitting devices. The light emitting devices are configured to emit germicidal radiation to irradiate the microplate, which is configured to be positioned below the modular light engine inside a chamber of the microplate irradiation system. In this way, a uniform intensity of germicidal radiation may be output by light emitting devices, resulting in disruption of contaminating nucleic acids present in the microplate.

摘要： A liquid chromatography flow cell including an integrated light source and an integrated detection chamber. The integrated light source includes a plurality of light emitting diodes (LEDs), wherein each LED emits light of a specific wavelength. The light emitted from the integrated light source is directed to pass through a sample in a flow chamber of the flow cell without any optical conditioning, and the light not absorbed by the sample flows out of the flow chamber directly into the integrated detection chamber, where an intensity of the unabsorbed light is measured by detectors coupled to the integrated chamber.
