GNR Spectrometer Service, Repair & Calibration
Verichek is the authorized GNR distributor for the U.S. and Canada — and we service the instruments we sell. We cover the GNR spectrometer line, including the S6 Sirius 500, E3 Esaport, and AREX series, with calibration, repair, and spare parts, all backed by ISO 17025 accreditation.
Our GNR Spectrometer Services
GNR has built precision OES, XRD, and XRF instruments since 1984. As their distributor across the U.S. and Canada, Verichek gives GNR owners a single source for calibration, repair, and parts — handled by technicians who know these instruments because we sell and install them, under ISO 17025 accredited procedures.
Calibration & Repairs
Whether your instrument is due for a routine PM or needs a full repair, we handle it across the GNR line — S6 Sirius 500, E3 Esaport, AREX series — with every calibration performed under ISO 17025 accreditation.
Spare Parts
Because we distribute GNR, we pull parts straight from the source. That keeps your repair on schedule instead of waiting on components routed through a third party.
Service All GNR Spectrometers
One provider for the whole lineup. Our technicians work across every GNR spectrometer we sell — from the S6 Sirius 500 to the AREX series and the rest of the range.
ISO 17025 Accredited for OES Calibration
Every calibration is run to ISO/IEC 17025 standards, and the ANAB-accredited certificate you receive holds up to quality management reviews, customer audits, and regulatory documentation.
Common Issues with GNR Spectrometers
Like any spark OES system, GNR instruments need regular attention to keep readings accurate. Here’s what our technicians see and correct most often.
Calibration Drift
Readings on a spark OES system shift gradually with use, and heavy production schedules speed that up. Routine recalibration brings your GNR instrument back in line and keeps results traceable.
Spark Stand or Electrode Issues
Buildup and wear at the spark stand quietly erode measurement consistency. We clean, inspect, and rebuild spark stand and electrode components so every burn reads true.
Optical System Degradation
Dust and wear along the optical path pull intensity readings off over time. We service the optics end to end to restore measurement reliability.
