Preferred Label : preconcentration coefficient;
Detailed label : preconcentration coefficient of a desired microcomponent in trace analysis;
IUPAC definition : This is defined as \[K \frac{Q_{{T}}/Q_{{M}}}{Q_{{T}} {{o}}/Q_{{M}} {{o}}}\] where
Q T and Q T o are the quantities of the microcomponent in the concentrate and in the
sample, respectively (mass units or concentration units), and Q M o and Q M and are
the quantities of the matrix before and after preconcentration, respectively. If the
recovery is 100%, K QMo/QM. The terms enrichment coefficient and enrichment factor
are not recommended.;
