It really is most likely secure to foretell that the way forward for chemistry is associated with the excited states of molecules and to different brief lived species, ions and loose radicals. Molecules have just one floor country yet many excited states. even though huge the scope of standard, flooring nation chemistry can be, above and past it lies the realm of excited states, each having its personal chemis­ test.

Of course, other considerations should be used if they are more appropriate. 9) are, therefore, of value in choosing the lower limits for measurement. When such standards do not exist, the user should normally still specify a lower limit, but bearing in mind the point made above that as limits are decreased, greater analytical complexity and cost usually result. 3). It is of interest to note that a Directive of the European Community on the sampling and analysis of surface waters 24 specifies the limits of detection required of analytical methods.

3. 25CL . 3. 3CL. 25CL . This inconsistency could be eliminated, for example, by using a slightly different confidence level to define the limit of detection, but this complication does not seem worthwhile. If such target values are interpreted with commonsense, no difficulty should be caused. In any event, we would stress that, in our view, the primary targets should be those directly concerned with the required precision and bias of analytical results. The equation of C L and LD provides a check on the reasonableness of those targets with respect to the power of detection.
