We developed a method of sample preparation using epoxy compound, which was validated in two steps. First, we studied the homogeneity within samples by scanning tubes filled with radioactive epoxy. We found within-sample homogeneity better than 2%. Then, we studied the homogeneity between samples during a 4.5 h dispensing time. The homogeneity between samples was found to be better than 2%. This study demonstrates that we have a validated method, which assures the traceability of epoxy samples.
我们开发了一种使用环氧化合物的样品制备方法，并分两步进行了验证。首先，我们通过扫描装有放射性环氧化合物的试管来研究样品内部的均匀性。我们发现样品内部均匀性优于2%。然后，我们在4.5小时的分配时间内研究了样品之间的均匀性。发现样品之间的均匀性优于2%。这项研究表明我们拥有一种经过验证的方法，可确保环氧化合物样品的可追溯性。
