Abstract
In one aspect, an ion source for use in a mass spectrometry system is disclosed, which comprises a housing, a first and a second ion probe coupled to said housing, and a first and a second emitter configured for coupling, respectively, to said first and second ion probes. The first ion probe is configured for receiving a sample at a flow rate in nanoflow regime and the second ion probe is configured for receiving a sample at a flow rate above the nanoflow regime. Each of the ion probes includes a discharge end (herein also referred to as the discharge tip) for ionizing at least one constituent of the received sample. In some embodiment, each ion probe receives the sample from a liquid chromatography (LC) column. Further, the ion probes can be interchangeably disposed within the housing.
