76 Agilent 6200 Series TOF and 6500 Series Q-TOF LC/MS System Concepts Guide

3 Methods with Acquisition Parameters

General TOF and Q-TOF parameters

You enter general TOF and Q-TOF parameters on the General

tab of either the TOF tab or the Q-TOF tab in the Method Editor

window.

Profile vs. centroid spectra

You can save mass spectral data as whole peaks over the mass

range of the peak, or you can save only the data for the mass

whose intensity appears in the “middle” of the peak. To limit the

number of peaks whose centroid data are saved or appear in the

Spectrum Plot window (line spectra), you can set an absolute or

relative threshold for both MS and MS/MS data.

Ion source parameters

See the online Help to view

recommended parameter values

for each ion source.

You can use several different sources with the Agilent TOF and

Q-TOF LC/MS system:

• ESI

• Dual ESI

• AJS ESI

• Dual AJS ESI

• APCI
