Abstract: This paper presents a comprehensive evaluation of measurement uncertainty in laboratory instruments and analytical methods, focusing on volumetric, chromatographic, and gravimetric techniques. The study emphasizes the importance of accurate measurement in ensuring the reliability of analytical results, highlighting various sources of uncertainty, including calibration errors, sample preparation inconsistencies, and environmental factors. Through detailed case studies, such as the assessment of uncertainty in ion chromatography for determining chloride and sulfate ions, as well as the preparation of standard solutions, the paper illustrates practical strategies for quantifying and minimizing uncertainty. The findings underscore the critical role of uncertainty management in laboratory practices, suggesting that improved methodologies and standardization can enhance data quality and compliance with regulatory requirements. The study calls for further research into advanced calibration techniques and the integration of technology in uncertainty analysis, aiming to foster a culture of quality assurance in laboratory settings.
