Empower 3: How to calculate the detector noise and drift? - WKB205246

OBJECTIVE or GOAL

• Calculate the detector noise and drift using Empower

ENVIRONMENT

• Empower 3

PROCEDURE

1. Analysis is performed in 5 minutes using the immediate injection function (injection operation is not performed while data is captured).
2. Set the Segment Width from 2 to 5 min, etc. on the Noise and Drift tab of the Processing Method.
3. After performing the processing and reviewing the result data, open the Window menu> Results to check the detector noise and detector drift in the Chromatogram Result table.
The unit is the same as the vertical axis for the detector, so if you want to scale to μV, display the Scale to μV field in the same table to convert.
* If the above field is not displayed in the Chromatogram Result table, right-click on the Chromatogram Result table and select Properties.
From the Hidden Columns on the Table Properties screen, clear the check boxes for "Detector Noise", "Detector Drift", and "Scale to µV".
