Welcome > Products > HTOF


The HTOF is our high-resolution platform.

THe ion optics and power supplies allow the user to alternate between operating modes, depending on desired speed, sensitivity and mass resolving power. 

While larger than the CTOF, this instrument has also proven to be a powerful option for field-portable applications demanding high mass accuracy and resolving power.1,2
