TOF mass spectrometry

[ScientistamI]

Hello

 

I was asked if a longer path in a TOF spectrometry gives a better resolution. I thought it was true, because the separation between the heavier and the lighter ions is more clear.

 

Is this right?

 

Thank you

Sounds plausible from what I know of it. Place the laser at the uttermost possible place near the end of the path. It'd also be dependent on the capabilities of your laser, imo.

Laser placement should not influence resolution. At best it affects ionization. A longer path does allow better mass separation, in principle, at least.

 

Also,not all TOFs use laser ionization.
