The transformation is applied to the data output in real time. The data
output is raised to the selected power.
As a standard, the Power Function is set to 1.0. For most applications
and compounds, this is a good universal setting.
Guidelines for selecting a power function value
To optimize the power function value, observe the following guidelines:
•
An optimal power function value improves the linearity of response
over a given range of interest.
•
Selecting the optimal value depends primarily on the analysis
conditions and the desired range of quantitation.
6.7.8 Baseline Noise
Baseline noise can originate from many factors. To minimize the
baseline noise, observe the following:
•
The quality of the mobile phase has a major impact on the
performance of the detector. Only use mobile phases of the highest
quality available. Keep impurities and contaminants to a minimum.
Follow the
Mobile Phase Guidelines for the Detector in section 6.5.1,
page 95 .
•
Flush the system modules at regular intervals to remove any non-
volatile residues from the mobile phase, if applicable.
• Follow the maintenance schedules to keep the system modules in
optimum performance state.
•
Keep the supplied gas in optimum quality for the detector.
