One common characteristic of many advanced scientific techniques, as indicated in Table 2, is that they are applied at the measurement frontier, where the net signal (S) is comparable to the residual background or blank (B) effect. The problem is compounded because (a) one or a few measurements are generally relied upon to estimate the blank—especially when samples are costly or difficult to obtain, and (b) the uncertainty associated with the observed blank is assumed normal and random and calculated either from counting statistics or replication with just a few degrees of freedom. (The disastrous consequences which may follow such naive faith in the stability of the blank are nowhere better illustrated than in trace chemical analysis, where S B is often the rule [10].) For radioactivity (or mass spectrometric) counting techniques it can be shown that the smallest detectable non-Poisson random error component is approximately 6, where ...

Every marketed product has a level of endotoxin tolerated based on the minimum pyrogenic dose and amount of the drug to be administered as per Food and Drug Administration (FDA) guidelines [19]. However, there are none for the more advanced chemical assays described here. Indeed there are only a few highly specialized university laboratories that currently have experience in trace chemical analysis of LPS and PG. There are no commercial testing laboratories. Simplification and automation will allow more widespread availability of these methods.

A Xany insights into early civilizations have been provided by the study of ceramics. Various physical and chemical methods are considered standard techniques for modem archaeology (I, 2). The macroanalysis, microanalysis, and trace chemical analysis of artifacts have added greatly to the understanding of prehistoric civilizations (3-6). The chemical techniques used for ceramic analysis have included spark source mass spectrometry (7) ...
