Project: Report on the certification of the thyroxine concentrations in human serum based lyophilized Reference Materials (RMs 372, 373 and 374) and the monitoring of their stability.
- project duration
- 31-DEC-99 – 31-DEC-99
- The report on the certification of the thyroxine concentrations in RMs 372, 373 and 374 contains the description of the RMs with details on the production and lyophilization process, on the homogeneity and stability, on the certification procedure and the used analytical methods. The results of certification are presented as wall as their statistical treatment. The stability is derived from analysis of samples submitted to accelerated degradation conditions by conservation under thermic stress.
