In general, use the mixed mode operation (MM-ES+APCI setting with Signal 1) instead of
alternating MM-ES (Signal 1) and MM-APCI (Signal 2) mode switching. Two times as many
scans are obtained during elution of a chromatographic peak, and no delay is needed
between scans, resulting in better data. It is rarely necessary to know whether a compound
responds purely in ESI or APCI modes on a chromatographic time scale.
