Any dealer should be able to answer these in writing. Our answers are printed beside each one.
| Ask this | Why it matters | Dynode |
|---|---|---|
| Which condition tier? | Refurbished, tested and as-is are not synonyms. A unit that was only powered on is not refurbished. | Every listing states its tier, with the fixed definition printed beside it. |
| Can I see the test data? | A chromatogram run on the actual unit is the only evidence it meets spec. Anything else is a description. | Included with every system. Retention times, transitions, signal-to-noise. |
| What is the model number? | A listing title is written for search. The model and serial identify what is being sold. | Every listing identifies the unit by model number and serial. |
| What is the price? | A withheld price cannot be compared against the market before an enquiry. | Published on every listing. Make Offer is a first-class state, not a substitute. |
| Who verified it, and where? | Confirming that a system powers on is not the same as verifying it to specification. | Chromatography-verified in our in-house lab, operating to ISO 17025 standards. |
| What does the warranty cover? | A thirty-day term covers shipping damage. Component failures generally appear later than that. | 90 days parts and labor. 180 days with IQ/OQ qualification. |
| Who services it afterwards? | An instrument without an install path cannot be commissioned on arrival. | Install and service nationwide through our service partner. |
| Is calibration traceable? | A validated method requires a traceable calibration chain. | NIST-traceable calibration available. |
| What if it arrives wrong? | The return term is the part of a listing that carries cost for the seller. | 60-day returns. Free U.S. shipping, excluding Hawaii and Alaska. |
Every listing states its condition tier and its price. If the system you need is not on the floor, we source it to spec from our supply network.
