The precision was assessed at different levels by intra-assay (repeatability) and inter-assay and between analysts (intermediate precision). The precision of the method is appropriate because it presented a RSD of 4.53% (37, 39, 40) for intra-assay; for inter-assay precision the F calculated was smaller than the F critical, for the precision between analysts the t calculated was less than the t critical, as shown in Table5.
