PerkinElmer NexION 350-Series ICP-MS — Auction Analysis
The evidence supports a NexION 300/350-generation ICP-MS with a Lenovo workstation and PolyScience chiller, but the exact sub-variant, external roughing pump, autosampler, software transferability, current vacuum performance, and full workflow remain unresolved. Increasing maintenance frequency makes the $13,262 closing high bid too aggressive against a roughly $5,000 blind ceiling.
Analysis snapshot · Historical — observed August 27, 2026. The source records a closing high bid, but award or settlement is not independently established. The original observed price, evidence, economics, and recommendation remain exactly as recorded and are not current.

Auction snapshot
Detailed bid history reached a $13,262 closing high bid and visibly contains bidder IDs 1 through 8. That evidence replaces the stale summary without implying award or settlement.
Dealer values for complete, tested ICP-MS packages do not justify aggressive blind bids on a system with unresolved workflow components and worsening maintenance history.

How independent review worksHow evidence is classified
Seller facts, photo-derived observations, manufacturer context, unknowns, and LotCaliper assumptions remain explicitly separated.
Photo Derived
Photo-derived
- NexION-family chassis, sample-introduction area, plumbing, Lenovo workstation, keyboard, and PolyScience chiller.
- Exterior completeness does not establish vacuum or analytical performance.
Not Established
Not established
- Exact 350Q/350X/350D/350S suffix, external roughing pump, autosampler, complete sample-introduction inventory, software transferability, and workstation communication.
- Current vacuum, plasma, tune, calibration, sensitivity, background, or stability performance.
Manufacturer Context
Independent context
- PerkinElmer continues to publish NexION 300/350-family consumables context, which supports residual service/parts utility but not turnkey support for this exact system.
Lotcaliper Assumption
LotCaliper assumptions
- $20,000 conservative gross resale.
- $8,000 non-acquisition burden excluding selling fees and hammer; ~$5,000 maximum hammer.
Equipment identity
Mass Spectrometry · quantity 1
PerkinElmer NexION 350-series ICP-MS; seller string NEXION 3500, exact suffix unresolved
Identity confidence: Medium High
Identity evidence
Seller identifies NEXION 3500, serial 850N5080601; photographs are consistent with the NexION 300/350 generation but do not resolve a Q/X/D/S suffix.

Sensitivity and robustness
Fails
The modeled economics fail the standard reseller requirements under the stated assumptions.
Blind/as-is model
- Max hammer
- $5,000
- Gross resale model
- $20,000
At the $5,000 ceiling, modeled profit is about $4,000 and ROI about 30.8%. At the preserved $13,262 closing high bid, modeled profit is about negative $4,262 and ROI about negative 20%.
Costs and maximum bid
| Transaction / operating cost | Amount | Basis |
|---|---|---|
| Selling Fees | $3,000 | LotCaliper assumption: 15% of modeled gross resale. |
| Shipping | $1,800 | LotCaliper pickup, packing, rigging, and inbound-logistics reserve; not a carrier or GSA quote. |
| Testing Repair Reserve | $2,500 | LotCaliper functional-test and diagnostic reserve. |
| Risk Buffer | $3,700 | Increasing maintenance, unresolved vacuum and sample workflow, exact configuration, software transferability, specialist service, and repair risk. |

This is a reseller ceiling, not a prediction of the auction's closing price. Any buyer premium or other unquoted acquisition charge must be deducted before bidding.
Workflow completeness, service trajectory, and economics
Resale-grade verification requires normal rough and high vacuum, a stable chiller and plasma/RF system, serviceable sample-introduction and interface parts, usable control software, successful tune/calibration, and acceptable standards performance. None is established by exterior photos or a last-known-operational statement.
- Use NexION 350-series/family wording; do not assign an unsupported Q/X/D/S suffix.
- Treat the autosampler and external roughing pump as not evidenced, not confirmed missing.
- Preserve the $13,262 detailed closing high bid instead of the stale summary.
Recommendation and rationale
Snapshot decision
SKIPSKIP: the $13,262 closing high bid is far above the roughly $5,000 blind ceiling for an incompletely documented legacy ICP-MS with worsening maintenance history and unresolved workflow components.

Market support assesses how well the available evidence supports the resale assumption. Exact third-party marketplace records may be omitted when source-use rights are unclear. Each dimension uses the published methodology rubric; a confidence label measures the strength and boundedness of its evidence, not the likelihood of a profitable outcome.
Risks and unknowns
High · Exact Variant Unresolved
The exact NexION 350-series suffix is unresolved.
Seller string and photos do not establish Q/X/D/S configuration.
High · Functionality Unverified
Current vacuum, plasma, tune, sensitivity, software communication, and analytical performance are unverified.
Last-known operation is not a current test.
High · Maintenance Trajectory Negative
Maintenance had become increasingly frequent.
Seller-reported pre-decommissioning history.
High · Vacuum Component Completeness Unknown
Vacuum-workflow completeness is unresolved.
No separate roughing pump is evidenced.
High · Software Transferability Unknown
Installed software is reported but transferability and instrument communication are unresolved.
No license or live communication evidence.
Medium · Autosampler Not Evidenced
No autosampler is evidenced.
Photo review; not treated as confirmed missing.
High · Specialist Service Risk
Commissioning and repair require specialist ICP-MS capability.
Vacuum, plasma, sample introduction, interface, and detector systems require integrated verification.
