Qualification and calibration

Our polarimeters are calibrated at factory with quartz control plates, certified by the German Metrology Institute (Physikalisch-Technischen Bundesanstalt PTB), which is the highest authority for metrology in Germany, and are delivered with a calibration report.

On request, a service technician of SCHMIDT + HAENSCH or one of our representatives can put into operation the instrument and can prove its analytical performance. For documentation purposes, the documents:

  • Installation Qualification (IQ),
  • Operational Qualification (OQ) and
  • Performance Qualification (PQ) can be completed together with the customer.

For periodic checks of the instrument, we recommend the purchase of a quartz control plate, that we can deliver, and a periodic check of the calibration. The quartz control plate is delivered with a factory certificate. On request, the German Metrology Institute (PTB) can certify the quartz control plate for an additional fee.
