HDR-DAD Solution - Data Analysis

The HDR-DAD solution offers the following sections for Data Analysis:
• Three separate signal groups for HDR, DAD
• Spectra information

The flow from DAD
calculates the chromatogram from DAD
HDR-chromatogram always starts at earliest with the signal of DAD
In spite of this, ChemStation and EZChrom display the delay time differential.

The HDR-DAD chromatogram shows a short gap at the beginning of the signal. This
reflects the fact that the combined HDR signal can only start as it is delayed by the
delay time between the detectors. Whereas the signals of the single detectors start
immediately at t = 0 min.
See Figure 24 on page 46.
The HDR-DAD chromatograms always start at t = 0 min and shows a short gap at the
end of the signal.
See Figure 25 on page 46.
