Variable Wavelength Detectors (VC-D40, VF-D40)
Operating Manual Page 87
Consider the following, when operating the detector in multi-
wavelength mode:
• Each additional channel reduces the maximum possible data
collection rate, and leads to an increased baseline noise.
• Switching the optical grating permanently between the wavelengths
can lead to wear on the mechanical parts of the detector in the long
term. The multi-channel operation mode is therefore
only
recommended for method development and peak-purity analysis,
but
not for continuous routine operation.
• As an alternative, you can switch the wavelengths as often as
required in a single data channel in the Chromeleon software.
For further information on wavelength switching and single-
wavelength operation, see
Single-Channel Mode ( } page 86) , and
the Chromeleon Help .
TIP The optical filters for eliminating higher-order wavelengths are
moved automatically into the light path. This applies for multi-channel
mode, too.
