Defining Further QNT Settings for MS

Handling the Retention Time Delay as against a second detector

You can use the Delay Time option on the General tab page to take the retention time difference into account. This is the time needed by the substances to travel from the first detector, for example, to the MSQ Mass Spectrometer.

Defining Peaks via Mass Spectra

For peak identification via mass spectra, use the six MS columns:

• Mass Peak 1 (as well as Mass Peak 2 and Mass Peak 3)

• MS threshold

• MS filter conditions

• Check MS retention times
