Edit the Timetable (LC/MS)

Use this Timetable to specify that the calibrant is on so that you can acquire in-acquisition calibration spectra or to change the direction of the diverter valve during the run to send the stream either to the MS or to Waste.

During a run, to control when the stream from the LC is going to the MS, set the diverter valve to only send the LC stream to the MS during certain times during the run.
