Description
Evident BTX III XRD Analyzer Repair
The BTX III is the benchtop counterpart to the TERRA II, delivering the same analytical performance in a 12.5 kg laboratory package roughly 30 by 17 by 47 cm. It runs a Cu target at 30 kV and 20 W, covers about 5 to 55 degrees 2-theta at around 0.2 degrees FWHM into a 1024 by 256 pixel Peltier-cooled 2D CCD, and offers XRF from 3 to 25 keV, with SwiftMin providing automated phase identification and quantification on the instrument.
June Company’s certified technicians repair the BTX III for analytical laboratories, cement and minerals producers, universities and industrial quality control groups. We diagnose and repair at the board and component level, and every instrument is functionally verified before it ships back.
Common BTX III problems we fix
- X-ray tube faults — reduced output or complete failure, extending count times or halting analysis.
- CCD detector faults — dead pixels, elevated noise or cooling loss degrading peak resolution.
- Cooling system faults — Peltier performance dropping, which raises the noise floor as the instrument runs.
- Sample chamber faults — the sample presentation system failing to hold or vibrate powder correctly.
- Calibration and alignment drift — 2-theta shift producing misidentified phases or poor quantification.
- Control electronics faults — board-level failures that stop acquisition or corrupt data.
- Software and storage faults — SwiftMin not launching, libraries not loading or results not writing.
- Communication faults — wireless or wired connections to the host PC dropping mid-run.
- Safety interlock faults — interlocks failing and correctly preventing operation.
- Power supply faults — instability in the high-voltage supply, which shows as inconsistent results rather than a clean failure.
FAQs
Is a BTX III economical to repair against replacement? Almost always. The mechanical platform is durable, and most faults are the detector cooling, the tube or the sample chamber rather than the whole instrument. We quote before any work.
Can you supply a calibration report? We verify against reference standards before return and report the results. A formal accredited calibration is a separate service we can advise on.
Do you repair the portable TERRA II as well? Yes. They share most of their analytical hardware.
Every repair is backed by a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
