*Needs more writing. Tell me what this machine does, and why i might want to use it

The microTof-QII is equipped with ESI, APCI and nanoMate ion source, which enables detection of wide range of analytes from small organic molecules to large proteins.

Qualitative analysis of any ESI or ACPI compatible analytes.

High mass resolution resolution of 17,500-20,000 FWHM and a typical mass accuracy at 1-2ppm.

Not able to do quantification, sample need to compatible with ESI or APCI source.

Idea of target compounds.


      • Mass Resolution: 17,500-20,000 (FWHM)
      • Mass Accuracy: 1-2 ppm


Analysis for the Bruker MicrOTOF-QII is supported by Bruker DataAnalysis 4.1.
