The uncertainties on the absorbances (sample and standard), volumetric flasks and volumetric pipettes have virtually no influence on the overall uncertainty. The estimated uncertainty of the spectrophotometric method for determination of linezolid was adequate for the scope of the method....
The volumes of the volumetric flasks had only modest effect on the uncertainty, while the mass was an important source of the uncertainty. The contribution of the calibration equation to the total relative measurement uncertainty was 59.39% for the linear equation and 30.34% for the polynomial ...
The resulting solution was filtered into 100 mL volumetric flasks and diluted to volume with 4 vol.% HNO3. Then, 0.5 mL aliquot was transferred to a 15 mL polypropylene test tube and diluted with 9.5 mL of 2 vol.% HNO3. The final dilution factor was 20,000. Before analysis, 100 µL...
