System Details

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.

Why employ ms4sale?

Your MS options are far reaching, so why use Jaytee Biosciences? Unlike other providers of used MS equipment, we have the ability to completely:

This is because we employ both skilled engineers and experienced scientists, which allows us to provide a value added solution.

When we acquire an MS system, we are not simply re-listing for sale with a mark-up. We service,test and run the system, producing chromatographic and mass spectral data before we advertise. When our clients ask us whether a particular system is suitable for their application, we provide detailed information, and offer a pre-visit service whereby you send us your sample, which we run and prove for your benefit. Why? Because we can, and because it helps you make the right choices.

Ask yourself why other companies are only showing stock images, with no data or proof of performance - because we have the skills, you get the peace of mind and the ongoing support for your method.

Finally, this is at no added cost, since our pricing policy is flexible, and therefore competitive - a win/win!

Jaytee; No take overs/mergers in over 35 years - just professional, solid, skilled on going support.
