metadata.name: dc.description.abstract
metadata.value: Precision of quantitative chromatographic analysis using absolute calibration is determined by the
  reproducibility of absolute areas (heights) of analyte peaks. Their dispersion, mainly associated
  with losses on samples during injection, lead to an insufficient accuracy of quantitation. Solving
  this problem implies using an additional standard for absolute calibration. The proposed version
  is based on introducing of an additional standard to calibration and target samples and on the
  replacement of absolute peak areas with relative values, namely S(analyte) / S(additional standard).
  It is noteworthy there are no restrictions on the chemical origin of the additional standard.
  In this case, the mode proposed allows increasing precision (reduce random errors) of results, as
  well as reducing the number of replicates to achieve a required accuracy. Furthermore, there is
  no significant complication of the analytical procedure as a whole. Refs 10. Figs 3. Tables 3.
