The possibility of contaminating the sample with the elements under investigation during the various steps is a major risk in trace analysis. The precautions required in order to minimize this problem are similar to those already identified when dealing with biological materials used for total element determinations.

I.I.I. Biological Materials Used as Standards. For some analyses in clinical chemistry, pooled collections of serum or urine offer the only readily available standard materials, and for this purpose their content of these substances is first determined as accurately as possible. The composition of the biological material to be used as a standard is obtained by means of reference methods, but practical considerations thereafter prevent the daily checking of the standard serum, urine, etc., against these reference procedures. For the monitoring of reagent and instru-...

You are developing a procedure for determining traces of copper in biological materials using a wet digestion followed by measurement by atomic absorption spectrophotometry. In order to test the validity of the method, you obtain an NIST orchard leaves standard reference material and analyze this material. Five replicas are sampled and analyzed, and the mean of the results is found to be 10.8 ppm with a standard deviation of 0.7 ppm. The listed value is 11.7 ppm. Does your method give a statistically correct value at the 95% confidence level ...
