Instruments
Systems and modules, new and used
Two different purchases sit on this page, and they turn on different questions. On a used system the question is history: what it actually comes with, the front end, the software and licence, the source condition, and what the PM record shows. On a new one there is no history to check, so it moves to specification, warranty and who supports the instrument once it is on your bench. Either way, if a unit is not right for your application, I will say so before you spend the money.
Nothing here is held in stock, new or used. Everything is sourced against your specification, so you are not choosing from whatever happened to come in. Tell me the modules you need and the analyte you run, and I will come back with specific units, the configuration, the history where it applies, and the price. On anything new I state the warranty and what installation involves before you order, and on a GC autosampler I confirm in writing that it controls your GC and works with your software, because that is the part that decides whether it is any use to you. Photographs on this page are diagrams, not listings. When a unit is quoted, you get photographs of that unit.

LC-MS and LC-MS/MS
0Triple quadrupole and high resolution systems, used and refurbished, with PM history.
Browse lc-ms and lc-ms/ms →HPLC and UHPLC
0Complete stacks or single modules: pumps, autosamplers, detectors, column ovens.
Browse hplc and uhplc →GC and GC-MS
0Gas chromatographs and mass selective detectors, with the inlet and detector configuration stated.
Browse gc and gc-ms →GC autosamplers and modules
5New aftermarket liquid and headspace samplers and trays, sourced to order. These are not used units. Compatibility is the whole question on a sampler, so tell me the GC model and the software that controls it and I will confirm the fit in writing before quoting.
Browse gc autosamplers and modules →Not sure which you need
Tell me the symptom rather than the part. What the instrument is doing, the analyte, and the system it runs on. I quote from a wider catalogue than the pages here, so a thing not listed is not a thing I cannot get.
What I check before recommending a system or module
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.
Control and software
On a new module, which GC it drives and whether your chromatography software will see it. Confirmed in writing before a quote.
