Instruments
Used and refurbished systems, with the history stated
A used instrument is only a bargain if you know what you are buying. Every system I source is described by what it actually comes with: the front end, the software and licence, the source condition, and what the PM history shows. If a unit is not right for your application, I will say so before you spend the money.
LC-MS and LC-MS/MS
Triple quadrupole and high resolution systems, used and refurbished, with PM history.
Listings for lc-ms and lc-ms/ms are being loaded. Sourcing is live now, so send the specification and I will quote it.
HPLC and UHPLC
Complete stacks or single modules: pumps, autosamplers, detectors, column ovens.
Listings for hplc and uhplc are being loaded. Sourcing is live now, so send the specification and I will quote it.
GC and GC-MS
Gas chromatographs and mass selective detectors, with the inlet and detector configuration stated.
Listings for gc and gc-ms are being loaded. Sourcing is live now, so send the specification and I will quote it.
What I check before recommending a used system
What is included
Front-end LC or GC, autosampler, detectors, and whether the software licence transfers.
Source and flow path
Condition of the source, and how the system was shut down and stored.
Service history
Last PM, what was replaced, and whether parts are still supported.
Fit for your method
Sensitivity and configuration against the analyte you actually need to run.
