The following table describes the parameters in the Plot Chromatogram dialog box.

Parameter

Description

Spray Stability

Runs the spray stability evaluation.

The spray stability evaluation generates real-time graphs of the TIC, base peak, or user-defined m/z, including the relative standard deviation (RSD). The %RSD must be less than 15 percent for the spray stability evaluation to pass.

Default: Cleared

TIC

Plots the TIC (total ion current) chromatogram.

Base Peak

Plots the base peak chromatogram.

User Defined m/z

Plots the signal intensities of the ions you enter in the mass table as a function of time.

Mass Table

Mass

Available when the User Defined m/z option is selected.

Indicates up to 10 m/z values for the ion signal intensities that you want to plot.

Range: 20–2,000; default: 200
