If MALDI is used as an ionization method, then TOF as an analyzer is suitable since the MALDI creates singly charged ions which have high m/z ratio and only TOF can analyze that ions, and multichannel plate should be used because the TOF is very quick and MCP's duty time is enough to capture all ions.
Is there a kind of table about configurations similar to the example I gave above? A table with reasons would be great but not certainly necessary.
