| Abstract: | The uncertainty of measurement in determination of n-C_(12)H_(25)-C_9H_(13)NCl by RP-HPLC was evaluated.Sources of uncertainty of measurement were analyzed such as sampling volume,sample dilution volume,sample preparation,standard curve drawing,measurement repeatability.The components of the uncertainty of measurement were quantified and composed.The expanded uncertainty of measurement for n-C_(12)H_(25)-C_9H_(13)NCl was 5.4%. |
| Keywords: | uncertainty benzalkonium chloride RP-HPLC content evaluation |
