If the chromatographic system is suitably calibrated, then size characterization of elemental species is possible. SEC is a gentle method and normally does not result in a loss of element species or on-column alterations. It plays the predominant role when separating labile and weak metal-complex-ing biopolymers (Makarov and Szpunar 1998). 

Therefore, several active methods were developed for locating uranium-containing particles. Scanning electron microscopy (SEM) is one of the most powerful techniques used for locating uranium-containing particles. The sample is placed on a stub that is inserted into the vacuum chamber of the SEM and is scanned by an electron beam. Typical peaks are obtained whenever uranium-bearing particles are encountered so that they can be mapped and their coordinates recorded. Characterization of elemental composition can also be carried out by SEM, but for isotopic measurements the particles must be transferred to a suitable device (usually TIMS or ICPMS).

Methods of Identification.—It may be helpful to summarize the main means by which heavy elements can be characterized, before considering actual experimental results. We have already mentioned the calculated X-ray energies of Carlson et and the use of this information with modern high-resolution X-ray detectors should allow the unique characterization of elements up...
