SECTION 13 – Multi-wavelength plus
The multi-wavelength plus measurement mode allows the user to determine the concentration of a
sample using photometric readings at more than one wavelength. The mode will also show the ratio of
two readings; a reading that is commonly used to indicate the purity nucleic acids. The mode includes an
option to include a reference wavelength measurement in the available calculations. Following sample
measurement, the concentration and ratio calculations are displayed on the operating menu screen.
13.1 MODE SPECIFIC PARAMETERS
The multi-wavelength plus operating menu enables
measurement parameters to be changed. The utility
toolbar on the left hand side of the screen enables access
to printing, print setup options, results, methods and
autologging options. For more details on the different
functions of the utility toolbar refer to section 17.
The settings icon enables the wavelengths, number of wavelengths, units, resolution, dilution factor,
concentration calculation equation and concentration equation factors to be set. Following the completion
of a multi-wavelength measurement the calculation icon will display the expanded calculations for the
results shown on the operating menu screen and the individual photometric readings.
