18. mzPeak metadata instrument configurations¶

Describe the JSON format of instrument configurations used to acquire a mass spectrometry experiment

18.1 Use cases¶

This describes which components are engaged for a particular scan configuration. This includes the inlet and ion source which may be configured independently of the mass analyzer. This is also the place to note the MS:1000031|instrument model, MS:1000529|serial number and any MS:1000032|customization done to the hardware.

18.1.1 Multiple configurations¶

When handling an instrument with multiple mass analyzers like an MS:1003768|ion trap orbitrap instrument, there SHOULD be multiple 18.2.1 instrument_configuration instances.

An example with two configurations, one using the ion trap, one using the orbitrap
