ANALYTICAL METHODS USED FOR CERTIFICATION

• 14 MeV neutron activation analysis
• Hydrogen reduction
• Reducing fusion
• In addition, surface analysis by prompt (d,p) reaction were performed to test for the influence of surface oxygen.

INSTRUCTIONS FOR USE

The material is intended for quality control purposes, i.e. to demonstrate analytical proficiency. Before use, samples must be prepared on a lathe, according to recommended procedures described in the report EUR 6241 or chemically etched for 3 min at 20 °C in HCl (d = 1.2) and subsequently for 1 min at 70 °C in a mixture of equal parts of HNO3 (d = 1.4), CH3COOH (d = 1.06) and H3PO4 (d = 1.7), rinsed successively in 3 vessels of water and 3 vessels of methanol and dried in a warm air stream. Corrections for surface oxygen can then be neglected. The analysis should be performed as soon as possible after this treatment.

STORAGE

The material shall be stored at 18 °C in the dark. However, the European Commission cannot be held responsible for changes that happen during storage of the material at the customer's premises, especially of opened samples.
