Overview
Overview
Benefits of a multimode source
Figure 26 Multimode source.
The multimode source is an ion source for LC/MS that can operate as an APCI,
ESI or simultaneous APCI/ESI source. See Figure 26. The source is intended
to operate at normal chromatographic flow rates 50 to 2000 µL /min. It is
capable of fast reversing pos/neg switching. The multimode source can be run
in three different modes of operation (MM-ES, MM-APCI or MM-ES+APCI).
Why use the multimode source?
A single ion source with a single nebulizer performing MM-ES, MM-APCI, or
MM-ES+APCI
MM-ES to MM-APCI without source exchange
Operates in MM-ES only, MM-APCI only, or MM-ES+APCI mixed mode
Operates at typical HPLC flow rates up to 2 mL/min, even in MM-ES mode
Multimode source provides higher throughput for data requiring validation
in both MM-ES and MM-APCI
