Abstract
By introduction of the analysis solution in measured quantities in atomic absorption and atomic emission spectrometry, the quantitative sensitivity of these methods can be increased by an order of magnitude, while the concentration sensitivity remains unchanged. The required volume of sample (serum) is thereby considerably reduced. Using this method, serum electrolytes and certain trace elements can be determined simply and quickly in only a few microliters of serum. The automation of this micro-sample application (injection method) largely abolishes individual errors, and markedly shortens the time for the analysis of large series of samples. The determination of serum electrolytes and Li, using only 5-20 .mu.l of serum, is described.
