QED MS/MS with Reverse Energy Ramp (RER)
InverseCollision

CE
M/Z
The RER scan function linearly reduces the amount of collision energy (CE) while theproduct ions are scanned from low to high mass in Q3. The resulting spectrumcontains more fragment ions with high abundance in low mass region.

QED MS/MS Advantages on TSQ Quantum
9 Faster than a Q-trap
Does not require Dynamic fill timethat consumes cycle time
Excellent performance at low levels
9 RER yields rich product ion spectra
Library searchable MS/MS spectra
Fragment-rich product ion spectra for identification
No space charge
9 With unique H-SRM for precise parent ion selection Cleaner MS/MS spectra which are easier to interpret
