3.2.3. Precision
Precision of the method was checked through the repeatability
and reproducibility experiment. Repeatability of the method was
evaluated by three preparations of pumpkin seed oil samples,
and each preparation was analyzed in duplicate according to the
method. Reproducibility was evaluated by comparing the results
obtained for repeatability with the results of the same sample prepared
by different analysts during two different days. The difference
between two analysts was determined using t-test.
RSD% and mass differences of these experiments are acceptable.
Obtained results confirmed precision of the method due to multiple
preparation of the sample and preparation by different
analysts.
