Shimadzu LC-10/20 System 4 Using the control module
4.4.2 Method Setup - PDA
Fig 45: Method Setup - PDA
Start Wavelength
Defines the lowest value of the wavelength to be used for the acquisition
of spectra. This value also influences the lowest possible value of the
Wavelength parameter on the Method Setup - Acquisition tab for the
single- wavelength PDA detector signals. The value must be in range
<190, 799> and lower than the End Wavelength value.
End Wavelength
Defines the highest value of the wavelength to be used for the acquisition
of spectra. This value also influences the highest possible value of the
Wavelength parameter on the Method Setup - Acquisition tab for the
single- wavelength PDA detector signals. The value must be in range
<191, 800> and greater than the Start Wavelength value.
Wave Step
Sets the wavelength step for the PDA spectra gathering. The lowest
possible value is 1 nm.
Lamp
Defines the lamp type that will be used in the measurement. Possible
options are Off, D2, W and D2+W.
Sampling Rate
Defines the sampling rate of the PDA detector, set in the Hz.
Time Constant
Sets the amount of time from which will the raw spectra be averaged to get
one reported spectrum. The value should be set so that it is longer than it
