Start with a configuration map.
List the main platform, source, separation modules, pumps, autosampler, chiller and workstation. Identify the manufacturer and model of each. Mark items that are shared, missing or excluded from the proposed sale.
Practical preparation
A useful technical enquiry.
A few specific details can turn “an LC/MS for sale” into a configuration that can be reviewed sensibly. Use this guide to assemble the information already available to you.
Describe the evidence you already have.
If available, include recent tune or performance reports and service records, with dates. Explain what the instrument was doing when last used and describe known issues. A photograph of a powered display is not a substitute for a performance record.
Make software part of the discussion.
Record the acquisition and analysis software names and versions, the workstation and any licence information available. Transfer rights and support arrangements need to be confirmed for the specific system; do not assume they follow the hardware.
Plan specialist preparation separately.
Share whether the equipment is installed, stored or already disconnected. Identify site access and timing constraints. Agree qualified deinstallation, decontamination, packing and collection responsibilities before any work starts.
Start with the equipment you have.
Send the model, configuration, condition and location. Attach photographs and any relevant records to your email.
Agree the details before collection
Confirm what is available
“Last used for a run in June” says more than “good condition”. “Powers on” describes startup only. “Stored since removal” describes a history, not present performance. State what was actually observed and when.
Describe the configuration
Use the equipment categories to list the included modules and accessories. Platform; sources; LC modules; pumps; computer. Keep photographs matched to the equipment list and mark retained or shared items. Include the exact model rather than relying on the system family name.
Share the known condition
Describe the most recent use, known faults, missing parts and available records. Say “unknown” when that is the accurate answer. Do not restart or dismantle equipment just to make the enquiry. Avoid including research, patient or other confidential data in photographs and documents.
Agree the commercial scope
An initial enquiry starts a discussion. If a purchase is proposed, confirm the included items, price, payment timing, preparation, packing and collection responsibilities in writing. Do not assume a preliminary discussion commits either party to a transaction.
Coordinate the handover
Clear photographs show configuration and external condition. They do not prove analytical performance. Include both the images and a written status account, and flag components that were changed after the last documented use.
Questions before you start
Can I enquire without a complete service file?
Yes. Send the model, location and what you know about condition. State which records are available and which details remain unknown.
What if the instrument is still in use?
Include the expected release window and any dependency on replacement equipment. A discussion can begin before a collection date is agreed.
Can I send photographs and a spreadsheet?
Use the enquiry form for the initial details. Email photographs or an existing spreadsheet to the address on the contact page, with your enquiry reference. Remove unrelated or confidential information first.
Is collection or payment automatic?
No. Purchase suitability, terms, preparation and collection arrangements must be agreed for the specific equipment and location.
