Terms & Conditions

HPGe detectors

  • Detectors must be free from contamination and properly packaged for shipment to qualify for repair.
  • In order to establish criteria for effective diagnosis it is useful to benchmark system performance through certified manufacturer records or qualification documentation (current operating specifications are preferable but records of detector performance are also acceptable).
  • ANTECH advises shipping in the original transport box or other suitable shipping container in order to protect the detector from damage. In the event that neither is available, ANTECH can provide an alternative shipping container, for a cost of $250 per detector.
  • There will be an additional shipping cost for locations outside the USA. Please call the Denver office on +1 (303) 430 8184 for more details.

ANTECH repair

  • ANTECH will not perform any repairs, modifications or adjustments without prior customer approval.
  • Repairs other than those stated in the price list will be agreed prior to repair and are priced at hourly rates plus parts.
  • In the unlikely event that ANTECH is unable to repair an HPGe detector (perhaps due to crystal damage, mechanical fault or a customer decision not to authorise the repair) the customer will be charged the evaluation fee and any incurred costs for shipping and handling.

Evaluation and repair periods

  • Results of the 5-POINT EVALUATION will be conveyed to the customer within ten business days after the date on which ANTECH receives the HPGe detector.
  • Detector repair will typically be completed within twenty business days after the date on which ANTECH receives repair approval. Conventional pump and bake detector repair will be completed within fifteen business days after repair approval. These lead times may be longer if it is necessary to acquire parts from the original manufacturer
