Uv-Vis Spectrophotometer

With its distinctive and patented variable pathlength technology (VPT), the CTech™ SoloVPE® System unleashes the potential of Slope Spectroscopy. This variable pathlength solution is both simple and empowering, providing rapid and accurate results while avoiding costly dilution.input:
output: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), in contrast to the single value dependence of legacy UV-Vis methods.



A real-time analysis of the section curve is then conducted to confirm that it is linear in accordance with the Beer-Lambert law. The concentration of the sample is directly proportional to the linear region of the section curve, as determined by the sample extinction coefficient.



The outcome?input:
output:Concentration results are reported by the SoloVPE System in less than 60 seconds. The SoloVPE solution is suitable for a diverse array of sample types and concentrations, as it is capable of performing spectral and fixed-point measurements at wavelengths ranging from 190 nm to 1100 nm and pathlengths ranging from 5 microns to 15 millimeters. The SoloVPE System method has been demonstrated to be precise, accurate, and robust. Consequently, it is feasible to validate it in compliance with the ICH Q2(R1) standards.



The robust system-to-system consistency is demonstrated by the variable pathlength technology, which permits R2 values of ≥0.999.input:
output:Methods of Slope Spectroscopy: The first and only slope spectrometer that is capable of conducting measurements based on slope spectroscopy. The SoloVPE System capitalizes on slope results that are derived from multiple data points, rather than a single absorbance value.input:
output:Rapid Characterization of Samples: Characterize samples at various wavelengths in a timely manner
