Abstract: | It is observed for the first time from an extensive compilation that the detection limit ratios for odd/even atomic number neighbour elements are generally less than 1 for nearly all-stable elements of the periodic table (most are even less than 0.5), which is very similar to the odd-even effect in cosmic abundances. This systematic behaviour of detection limits can be explained by a simple relationship with physicochemical and environmental-geological factors. We propose that such a behaviour should be used in future as a fundamental criterion to evaluate the highly variable detection limit data for all chemical elements by a given analytical technique and the estimation of detection limits should be based on at least 30 or more measurements. |
