Solo VPE

Innovative UV/VIS/NIR-Spectrophotometer

Manufacturer: C Technologies Inc.

The SoloVPE system is the technological innovation behind the Slope Spectroscopy® technique. The employed method plots absorbance against pathlength data to determine a slope value for quantitation of sample concentration, delivering rapid and accurate results while avoiding costly dilution and background correction steps.

  • Robust and flexible UV/VIS-spectroscopy
  • No dilution or baseline correction necessary
  • Rapid results (<1 min)
  • antibody concentration range: 0.05 mg/ml to 300 mg/ml
  • Repeatability: ± 2%
  • 21 CFR Part 11 Compliant Software

    C Technologie`s SoloVPE (Variable Pathlength Extension) is an innovative analytical instrument for UV-Vis spectroscopy, employing the Slope Spectroscopy® method.

    By using varying the optical path, the SoloVPE performs a linear regression of absorption values vs. pathlengths to calculate a slope. Based on the Beer-Lambert Law, this enables a fast, simple and precies determination of either the concentration or the extinction coefficient. The broad pathlength range of 0.005 mm - 15.000 mm allows for a direct measurement of even highly concentrated samples up to 300 mg/ml. This eliminates the need for time consuming dilution steps and baseline corrections.

    During the measurement, the SoloVPE automatically determines the lineare absorption range to take the data points. The quality of the measurement can directly be verified by the coefficient of determination (R2 value).

    Numerous companies all over the world are already employing the SoloVPE in different areas (R&D, MS&T, AD, QC) for a broad spectrum of validated methods.

    The SecureVPE software package provides the necessary 21 CFR, Part 11 compliance, so that the SoloVPE is also widely spread in GMP regulated environments.
