2.7.3. Precision and accuracy
Precision of the method for each sweetener was evaluated
according to relative standard deviation (RSD). Six blank samples,
which were added to standards at low, medium, and high level,
were prepared. Consecutive injections for six samples at low, medium,
and high levels in one day gave the precision of intraday, and
repetitive injections for six samples at low, medium, and high
levels in six days gave the precision of interday.
