Bristol-Myers Squibb: UV-Vis Based Determination of Protein Concentration

No longer are scientists bound to the time-consuming, errorprone use of dilution factors and fixed-pathlength measurements in determining the concentration of an analyte in solution. Using the slope spectroscopy technique, the Solo VPE system (from C Technologies) offers a new method of determining analyte concentration based on the Beer–Lambert law and slope derived from absorbance measurements made at multiple pathlengths.
