Evaluation of Uncertainty Measurement in Content Determination of Aciclovir Tablets by UV

Abstract

Abstract: Objective: To establish a method for the evaluation of the uncertainty of the zinc content determaination of the rice. The influencing factors on the uncertainty in the procedure of the content determination were evaluated, including repeatability of results of measurements, the dilated volume of sample, the weight of sample, the measurement for concertration of zinc by standard curve. The expanded uncertainty U95 was 2.5 mg/kg, the coverage factor was 2. The evaluation is reliable.

Key words: uncertainty of measurement, zinc, atomic absorb spectrometry, rice, evaluation
