170 Knauer Instrument Control Method Options<br />

Knauer Instrument Control Method Options<br />

General Settings<br />

Some general method settings belong exclusively to the Knauer<br />

instrument control. They are accessible by the METHOD menu.<br />

Runtime Settings<br />

The runtime setting options are general settings. The selection is valid for<br />

all ChromGate methods until it is changed.<br />

Emergency during a run options<br />

In the case that an emergency situation is detected, the software can be<br />

forced to stop all pumps and/or to switch off all lamps and/or switch off all<br />

ovens.<br />

If enabled, this option is valid for the currently used computer.<br />

Direct Control during a run<br />

If this option is enabled, all devices can be controlled manually using the<br />

Direct control section of the device’s instrument status tab. The direct<br />

control during a run option is a valuable tool for method development but<br />

can also lead to the possibility for unintended changes to the method. For<br />

this reason, it is recommended that this option not be enabled, especially<br />

for routine methods. All changes during a run will be added to the<br />

instrument activity log, but cannot be stored in the original/acquisition<br />

method, attached to the data file. This may not meet your GLP/GMP<br />

requirements.<br />

Save Changes in time table<br />

This option can only be enabled/disabled, if the “Enabled” checkbox for<br />

“Direct Control during a run” is activated. If the “Save changes…”-Option<br />

is checked, any method changes by direct control will be saved in the<br />

method. Otherwise the changes only can be monitored in the instrument<br />

activity log and in the audit trail, refer to the EZChrom reference manual.<br />

Due to that the changes cannot be stored in the method, which is<br />

attached as the original/acquisition method to the data file; we<br />

recommend reanalyzing the chromatogram with the changed method. All<br />

methods used to analyze a chromatogram, also will be added to the<br />

chromatogram data file and can be extracted as “From Results” in the<br />

Open Data dialog.
