The CTech™ SoloVPE® System unlocks the power of Slope Spectroscopy with its unique and patented variable pathlength technology (VPT). Avoid costly dilution with this simple, yet empowering variable pathlength solution that delivers rapid and accurate results. Unlike the single value dependence of legacy UV-Vis methods, the data-dense slope method characterizes samples by collecting multiple absorbance data points at several pathlengths to create a section curve (absorbance vs. pathlength plot). The section curve is then analyzed in real time to verify linearity in compliance with the Beer-Lambert law. The linear region of the section curve is directly proportional to the concentration of the sample based upon the sample extinction coefficient. The result? The SoloVPE System reports concentration results in less than 60 seconds. Capable of making spectral and fixed-point measurements at wavelengths between 190 nm and 1100 nm at pathlengths between 5 microns and 15 millimeters, the SoloVPE solution is adaptable to a wide range of sample types and concentrations. The SoloVPE System method has been proven to be accurate, precise, and robust. Therefore, it can easily and successfully be validated in accordance with ICH Q2(R1) requirements. The variable pathlength technology allows R2 values of ≥0.999, proving the robust system-to-system consistency. Slope Spectroscopy Methods: The first and only slope spectrometer, capable of Slope Spectroscopy-based measurements. The SoloVPE System takes advantage of slope results based upon multiple data points instead of a single absorbance value.
