Excel spreadsheet for Codex method criteria

As an alternative to specifying analytical methods in Codex Standards, Codex has adopted method criteria, i.e. Codex has a set of method performance characteristics for which there have been established numeric values. The laboratories can choose which method to use as long as the criteria are fulfilled. The method criteria are calculated based on the ML (maximum level) and the Horwitz' ratio. This Excel spreadsheet calculates the values for you.
