The IONICON hexapole ion guide
With PTR-TOFMS you can benefit from extraordinary sensitivity in combination with a high mass resolution that allows to separate substances and thus caters to their identification.
The new IONICON ION-GUIDE technology pushes both, the instrument's sensitivity and mass resolution to new extraordinary levels.
As electrostatic fields are incapable of focusing an ion beam in two dimensions, common lens systems in the transfer region between the PTR reaction chamber and the TOF mass spectrometer deteriorate the instrument's sensitivity because of ion losses. Hence, multipole ion guides have been invented for extremely efficient, virtually lossless transport of ions.
The ideal multipole is an IONICON hexapole
Hexapole ion guides, which are utilized in our instruments, are particularly preferable, because they transmit a broad range of ions and additionally focus them to a narrow beam. As a result not only the overall sensitivity is considerably increased, but due to favorable injection conditions into the mass spectrometer, also the mass resolution is improved.
