Metrohm MIRA XTR Handheld Raman Analyzer Repair

June Company repairs the Metrohm MIRA XTR at the component level — the 785 nm laser, the Orbital Raster Scan assembly, the detector, the optical bench and the control boards — 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 MIRA XTR earns its place in the field on two features and both change how it fails: the XTR algorithm pulls a Raman signal out of samples whose own fluorescence would otherwise bury it, and Orbital Raster Scan sweeps the laser across an area instead of parking it on one spot, so heterogeneous samples are represented properly and nothing gets burned. Both depend on laser stability and clean scanner movement, which is why a MIRA XTR rarely dies outright — it degrades, and the first thing anyone notices is match confidence falling on materials it used to call cleanly. We measure excitation power and detector response separately before quoting, because those two faults look identical from the outside and only one of them is expensive.

What is included with every MIRA XTR 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 known reference sample 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 MIRA XTR problems we fix

• Laser output degradation — 785 nm excitation power falling until spectra get noisy and match confidence drops.
• Orbital Raster Scan faults — the scanner no longer sweeping cleanly, so a heterogeneous sample reads as whatever sat under the beam.
• XTR fluorescence rejection falling away — samples it used to handle returning a sloping baseline and no usable peaks.
• Sapphire window and sampling interface damage — scratching or clouding where the sample actually meets the optics.
• Detector degradation — rising noise floor and falling sensitivity, worst on weak bands and trace components.
• Optical alignment drift — throughput falling away after a drop, with peaks no longer landing where the library expects.
• Battery, charging and power faults — shortened runtime, or shutdowns partway through a shift.
• Display and touchscreen failures — dim, dead or unresponsive panels, including digitizer faults that make it unusable in gloves.
• USB, Wi-Fi and Bluetooth faults — results not transferring to the host software, or the instrument not being recognised at all.
• Failed startup self-check or calibration verification — no longer verifying correctly against its internal reference standard.

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.

Match confidence has dropped across the board. Laser or detector? It can be either and they present almost identically. We measure excitation power and detector response separately rather than replacing the expensive part first — exactly the call component-level work is for.

Do you service the rest of the MIRA line? Yes. MIRA P, MIRA DS and the NanoRam instruments come through the same bench, and the laser, scanner and detector work carries across.
