No Dilutions
Measure highly concentrated samples directly without dilution.
Eliminate Background Correction
Buffer/ background correction only required in special circumstances.
Reduce Sample Prep
Direct measurements of highly concentrated samples saves time and consumables.
Rapid Results
Concentration results in about one minute.
Low Sample Volume
Method and sample vessel dependent ranging from <20 μl to 2 ml can be reclaimed.
Platform Technology
Confidently work system-to-system with +/- 2% repeatability.
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.
Rapid Sample Characterization: Rapidly characterize samples at different wavelengths and pathlengths using a single method.
Education/Support: On-site installation and training included with system purchase.
Linear Range Finder Technology: The system automatically identifies the linear region of section data sets to verify compliance with the Beer-Lambert law.
