Abstract: 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.
