Description:

The time required for a substance to travel from the detector cell of one detector to the detector cell of a second detector is referred to as Delay Time. If a third detector is installed, the delay time is the time between the detector cell of the first detector and the detector cell of the third detector.

Function:

Usually, a constant Flow is used. With constant flow, the delay time between two detectors is constant as well. In this case, it can be measured and entered on the General tab page in the QNT Editor (see The QNT Editor  The General Tab Page). Verify that a second detector (or channel) is specified in the Detector name field. Otherwise, you cannot enter a delay time.

The entered delay times can be positive or negative, depending on whether the detector directly following the column or any other detector is defined as 2nd detector.

 Note:

Entering a delay time for Flow Gradients does not make sense because the delay is not constant in this case. Follow the description in  Defining the QNT Method for Several Detectors.
