It follows that it is closely dependent on the noise (σ0) associated with the zero concentration (blank) measurement. This, from the foregoing discussion of precision, is readily estimated graphically, as in Fig. 2-3, or by calculation of the linear regression of IX! 954a c . Usually two standard deviations are taken as the confidence level and the detection limit is then defined as the concentration that gives rise to a signal equal to twice the standard deviation of blank fluctuations: thus at the detection limit Pc = 100% and c = 2σ0 (Fig.

However, the most meaningful estimate of a laboratory detection limit can be obtained, as described here, as part of the routine monitoring of laboratory precision. With duplicates carried through the complete analytical procedure this will take into account random errors introduced during sample decomposition as well as those generated during the final measurement. Sources of and reduction of random errors So far only the overall analytical precision, arising from random errors throughout sample preparation, decomposition and measurement, has been considered.

Laboratory swing mills and ball mills have the disadvantage of only being able to handle relatively small quantities (20—200 g) of material and sample bulk must sometimes be reduced accordingly by coning and quartering or splitting. Laboratory crushing and grinding equipment is made from a variety of materials (Table 3-1) and wear causing contamination of samples is inevitable. However, this is probably less of a problem than the contamination resulting from sample carryover, particularly if anomalous and background samples must be processed with the same equipment: preparation of assay samples on the same equipment is, of course, to be discouraged!
