Example of a Dynamic Peak Parking Setup
Figure 98 Example picture of the dynamic cut shift setup
The maximum shift of the IRTS is 0.57 min. This means the end of peak-based
area is at 2.80 min and the next time-based cut with reference to IRTS can be
placed at 2.8 + 0.57 = 3.37 min.
Here is an example of how fluctuations that occur during a run can be
compensated with the help of the IRTS and dynamic cut shifting.
The chromatograms below shows the results obtained from MassHunter Qual.
The top 1D chromatogram shows the original reference chromatogram the
method was based on. The middle 1D chromatogram indicates the RT shift.
The cut-markers image below show that time-based cuts were dynamically
shifted accordingly.
Table 11 IRTS
Peak-based start: 2.10 min
Peak-based end: 2.80 min
Expected time: 2.67 min
If a time-based cut shifts to the front and would enter the peak-based area
(bracket) the dynamic cut shift will not work.
