n/a |
Read-only |
Filter string as used in Thermo Finnigan aQa method. |
Tip:
Support for data compression is not available. Thus, the Step, MaxAutoStop, and Average commands cannot be set. Manual data acquisition is not possible, either. In addition, acquisition is started at the time 0.000 and stopped at the end of the program for all channels that deliver data according to an aQa method file. These channels do not appear in the Program Wizard or on the control panel.
