Waters MicroMass ZQ

The Waters MicroMass ZQ is a quadrupole mass analyzer designed to determine the mass-to-charge ratio (m/z) of diverse analytes.

The MicroMass ZQ delivers a liquid sample to the instrument’s analyzer source through an HPLC system or syringe pump. From there, sample molecules are ionized one of two modes: electrospray (ESI) or atmospheric pressure chemical ionization (APCI).

Sample molecules ionize in the solution before they reach the source and begin a desolvation process on entering the evacuated source while in ESI mode; while an electrical discharge inside the source ionizes the sample molecules and they undergo desolvation in APCI mode.

Once the ions reach the quadrupole, they are separated according to their mass-to-charge ratios. A photomultiplier then detects the mass-separated ions, amplifies their signals, and sends the mass information to the data system.

Please note: system includes vacuum pump.
