Used Waters Micromass ZQ 2000 Alliance LC Mass Spectrometer
This single quadrupole mass spectrometer from Micromass capable of performing up to 32 MS experiments in a single chromatographic run. See full calibration and quantification data in the images and pdf download.
Easily qualify and quantify small molecules - both inlet probes are quickly and easily interchangeable without breaking vacuum.
Flow rates on the ZQ are 5-1000µL/min (ESI).
ZQ Features
- Air Cooled System
- Mass Range 2000 amu
- Z Spray dual orthogonal sampling intereface provides unsurpassed sensitivity
- Vertically mounted liquid inlet probes to minimize tube length and peak dispersion
- MassLynx controlled, intergrated syringe pump for easy calibration, tuning and sample infusion
- Digital control of source gas flow rates
- MassLynx controlled divert valve/manual injection valve
- Differentially pumped vacuum system featuring singular air-cooled, split flow turbomolecular pump technology

Waters 2695 Alliance HPLC
The Waters Alliance 2695 Separations Module consists of a quarternary pump, degasser and a autosampler, capable of injecting from 5 x 24 2ml vials.
The Alliance four solvent in-line degasser offers a high efficiency alternative to helium sparging for the removal of dissolved gases from HPLC mobile phases.
