Installation Qualification is normally carried out once after the delivery and start-up of your instrument. In contrast, Operational Qualification is required at regular intervals in order to document proper instrument functioning and the reliability of the results. We offer Installation Qualification (IQ)/Operational Qualification (OQ) for all our current KRÜSS instruments throughout the whole of Europe.
