Abstract: ultraviolet (UV) based imaging method for determining protein concentrations of unknown protein samples based on automated multi-wavelength calibration. In various embodiments, a processor receives each of a standard set of wavelength data and an unknown set of wavelength data as recorded by a detector. Each standard set of wavelength data and unknown set of wavelength data defines a series of absorbance-to-wavelength value pairs across a first range of wavelengths selected from a range of a single-wavelength light beams of a UV spectra. The processor generates a multi-wavelength calibration model based on each of a first series of first absorbance-to-wavelength value pairs of the standard set of wavelength data. The processor implements the multi-wavelength calibration model to determine, for each unknown protein sample of the given unknown protein samples, a plurality of protein concentration values.

Abstract: Systems and methods that facilitate the automatic (or substantially automatic) preparation of a sample of a product containing molecules for analysis and automatic (or substantially automatic) performance of an assay of that sample. Thus, the preparation and analysis can be performed substantially in-real time, or, in other words, much more quickly than presently allowed by conventional systems and methods.
