Some analytical procedures cannot be logically classified into a hierarchical scheme. The reasons for this include the following:
- The procedure involves different techniques, dependent on the concentration of the analyte
- The procedure involves a single instrument, which is capable of different kinds of measurements
- The published data have been compiled from a variety of sources, and the techniques used cannot be identified
- The published value is obtained by numerical calculation, using analytical values obtained by different methods – the calculation may be as simple as a summation of oxides

The different kinds of analytical techniques have been classified hierarchically. Examples: “AAS”, “FA-NA”. Taken from the “Analytical_Techniques_SHARED” database table.
