Accurate Mass Measurement

There have been extensive discussions here on accurate mass
measurements by QToF and FTMS. How about Finnigan TSQ Quantum with
high resolution software (FWHH 0.1 u)? Is it good enough for small
molecule accurate mass determination?

What about ion traps? What resolution can we expect compared with QToF
and FTMS?
If ion conc. in the trap is low, can we get accurate mass with 5 ppm
or less on traps (90% times)?

Thanks in advance!
