st4713 ZQ 2000 with Alliance LC-MS from Waters

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

ZQ Specifications

Sensitivity 1 pg reserpine (see data above)
Mass range z/q 2 - 2000 amu
Ionization (ESI) Electrospray
Ion Positive or Negative
Spectral stability Mass accuracy to within 0.2 Da over a 24 hour period
Injector valve Controlled electronically
Control of source gas flow rates Digital

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.
