Displaying the Signal Parameters of a Mass Channel

Different channel types are available for Mass Spectrometers:

TICF channels (TICF 01 to TICF 09 for the MSQ or TICF_1 to TICF_4 for the aQa: data acquisition in Full-Scan mode)

SIM channels (SIM_01 to SIM_32: data acquisition in SIM mode)

TIC channel (total of all TICF or SIM channels)

MS_01 to MS_32 channels (data acquisition in full-scan mode)

Almost no parameters for mass spectrometer channels can be changed from the Control Panel. Select Axis/Decoration on the context menu of the signal plot to display the following parameters for the channels of a mass spectrometer:

Parameter	Description	Comment
Filter	Filter of the MS method (METH file).	No input possible, not even in the F8 dialog box.
FilterIndex	Number of the Filter of the MS method.	Only for the MS_01 to MS_32 channels (press F8): Select the number of the desired filter (1-9 for the MSQ or 1-4 for the aQa):
Min/MaxMass	Limits of the mass range that is acquired in this channel.	Only for MS channels MS_01 to MS_32 (press the F8 key): Enter the lower and/or upper mass range limit.
Polarity	Ionization polarity of the mass spectrometer.	No input possible, not even in the F8 dialog box.
Source Voltage	Voltage of the ion source of the mass spectrometer.	No input possible, not even in the F8 dialog box.

Press the F8 key or select Commands on the Control menu to display the following parameters:

Parameter	Description	Comment
Delta	Difference between the current signal value and the signal value one second before.	The value cannot be changed.
Retention	Indicates the current retention time.	The value cannot be changed.
Signal	Value indicates the current value of a Signal. UpperLimit and LowerLimit define the signal acquisition limits.	If signal acquisition limits are not met, the running batch is stopped and the emergency program is started.
