When the data collection rate is 20 Hz, select parameters that meet the
following criteria:
Where:
O
= Reference wavelength
BW = Reference bandwidth
For example, the following parameters are VALID:
Wavelength = 190 to 500 nm
Reference wavelength = 450 nm
Reference bandwidth = 50 nm
These parameters are valid because 190 to 500 nm is a range of
d
310 nm and
450 nm + 25 nm (50% of 50 nm) = 475 nm, which is less than 500 nm.
The following parameters are NOT VALID:
Wavelength = 190 to 600 nm
Reference wavelength = 750 nm
Reference bandwidth = 50 nm
These parameters are invalid because 190 to 600 nm is a range of more than
310 nm; also, 750 nm + 25 nm (50% of 50 nm) = 775 nm, which is greater
than 600 nm.
To troubleshoot:
Chromeleon cannot perform digital data acquisition of a 3D data field unless
the software includes the 3D Data Acquisition license. Contact Thermo Fisher
Scientific if you want to order this option.
