Description

HORIBA nanoPartica SZ-100V2 Nanoparticle Analyzer Repair

June Company repairs the HORIBA SZ-100V2 at the component level — the laser, the detector and its optics, the Peltier temperature stage, the sample cell assembly and the correlator electronics — rather than swapping modules until something works. Send us the instrument and you get a firm quote before anything is touched, a 90-day parts-and-labor warranty on the work, and NIST-traceable calibration included with most repairs. The evaluation fee is credited to the repair, and most instruments are back out the door in one to three business days.

Knowing the instrument is the difference between a repair and a parts swap. The SZ-100V2 does three jobs from one optical bench — particle size by dynamic light scattering, zeta potential by electrophoretic light scattering, and molecular weight — and they fail independently. That is the single most useful thing to know when one of them starts disagreeing with your expectations: a zeta cell with worn electrodes will give you bad mobility readings while size data stays perfectly good, and a Peltier stage two degrees off setpoint will bias every size result while zeta looks fine. Because size is derived through the Stokes-Einstein relation, and viscosity follows temperature, a thermal fault here does not announce itself — it just moves your answer. We check the thermal stage against setpoint as a matter of course.

What is included with every SZ-100V2 repair

• Component-level diagnosis and repair — board and component work by certified technicians, not module replacement.
• A firm quote before any work begins — including which subsystem failed and why, so the decision is yours.
• 90-day parts-and-labor warranty on everything we repair.
• NIST-traceable calibration included with most repairs.
• Functional testing against a certified particle size standard before the instrument ships back.
• Evaluation fee credited to the repair — it is not an extra charge on top.
• No forms and no account needed — send it in and we take it from there.
• Out-of-warranty and end-of-support instruments welcome — a large share of what comes through the bench.

Common SZ-100V2 problems we fix

• Zeta potential cell and electrode faults — electrode wear or fouling, which shifts mobility readings while size still looks correct.
• Peltier temperature control faults — the stage drifting off setpoint, which biases every result because size is derived through viscosity and viscosity follows temperature.
• Detector degradation — rising dark counts and falling sensitivity, worst on dilute or weakly scattering samples.
• Optical alignment drift — scattering volume no longer landing on the detector properly, costing count rate before anything fails.
• Cuvette holder and cell contamination — residue and scratching in the sample path, which reads as spurious large particles.
• Correlator and acquisition electronics faults — noisy or truncated correlation functions that will not fit cleanly.
• Communication and software faults — the instrument not being recognised by the host PC, or results not writing to the report.

FAQs

What does the evaluation involve, and what does it cost me? We bench-test the instrument, identify the failed subsystem and send you a firm price. The evaluation fee is credited to the repair if you go ahead, so the repair costs what the quote says and nothing more.

Sizes have shifted slightly but nothing has failed. What causes that? Temperature, most often. Size is calculated through viscosity and viscosity follows temperature, so a Peltier stage a couple of degrees out biases every result without any error appearing.

Zeta readings are wrong but size is fine. Is that one fault or two? Almost always one, and it is usually the zeta cell rather than the instrument. The electrodes wear and foul independently of the optics.
