Functions
This section introduces the functions of the UV-Vis Analyst.
Main Functions
Single wavelength photometric measurement
Go to a desired wavelength quickly and conveniently.
Photometric value display mode can be changed (%Transmittance or Absorbance).
Fixed Points Measurement
Multi-wavelength Photometric Measurement
Up to 20 wavelength points can be set up.
Results will be grouped into a table format automatically.
Concentration Measurement
2 methods to set up the regression curve.
Up to 20 standards to set up the regression curve. The UV-Vis Analyst will
calculate the working curve using a linear equation that fits the data. Enter factor
values to generate regression curve.
3 methods for curve fit.
Linear fit, Quadratic fit and Cubic fit.
Wavelength Scanning
Allow user to set scan step (0.1, 0.2, 0.5, 1.0 and 5.0nm).
Spectrum display mode can be changed (Wavelength-%Transmittance or
Wavelength-Absorbance).
Peaks and valleys will be automatically detected after scanning (User can define the
peak threshold).
Powerful spectrum processing functions are provided.
Time Scanning
Allow user to set scan Interval (0.5, 1.0, 2.0, 5.0, 10, 30 and 60s).
Spectrum display mode can be changed (Time-%Transmittance or
Time-Absorbance).
Peaks and valleys will be automatically detected after scanning (User can define the
peak threshold).
Powerful spectrum processing functions are provided.
