Image from “Apparatus For Separating Charged Particles Of Different Specific Charges” Patent number: 2939952

Instrument Calendar:

• Waters Q-TOF

Q-TOF provides:

• Intact protein mass determinations by direct ESI infusion and data analysis.
• Filtering of sample ions, based on their mass-to-charge ratio (m/z).
• Separation of ions in a quadrupole based on the stability of their trajectories in the oscillating electric fields that are applied to the rods.

Typical Applications:

• Where particular ions of interest are being studied because they can stay tuned on a single ion for extended periods of time.
• Liquid chromatography-mass spectrometry or gas chromatography-mass spectrometry where they serve as exceptionally high specificity detectors.
• Reasonably priced and make good multi-purpose instruments.
