Introduction• The quality requirements of the
fluid are controlled at the supply.• To control the evolution of some
chemical properties, especially interesting for the detector, chemical analyses can be demanded (see sampling form).
• To monitor the activation of the fluid, Radiation Protection will do regular analyses to ALL the stations.

• Regular analyses– To monitor the activation of the fluid.– To ALL the stations.
• Corrective maintenance– For safety reasons in a non-planned intervention.– Estimated time for the analyses during working hours: 2 hours – Estimated time for the analyses during not working hours: 3
hours – Authorization e-mail with analyses result will be sent to
