5.6 Special Functions in Chromeleon

This section provides a short overview of some special functions that Chromeleon supports
for the detector.
To learn more about ...

Optimizing the detector performance

Recording absorbance spectra
Predictive performance
Diagnostics Tests
Operational Qualification and Performance Qualification
All of these functions are available in the Commands dialog box (unless otherwise noted).
In addition, some functions are available also on the control panel for the detector. For
additional information about a function, see the Chromeleon Help.
5.6.1 Optimizing the Detector Performance
The performance of the detector can be optimized by careful selection of key operating
parameters. The table summarizes these parameters, indicates the performance
characteristics affected, and offers guidelines for selecting the parameters. For more
information, see the Chromeleon Help.
Operating Parameter
Data collection rate
Time constant
Wavelength
Baseline behavior
In Chromeleon, you can set the operating parameters manually in the Commands dialog
box for the detector (→ page 59) and on the VWD page of the Panel Tabset (→ page 61).
When you create a program with the Program Wizard, the wizard automatically calculates
the data collection rate and an appropriate time constant, based on the value you enter for
peak width at half-height.
