This study presents internal quality control of a semianalytical balance (GEHAKA BG400) using control charts. From 2013 to 2016, 2 weight standards were monitored before any balance operation. This work intended to evaluate if any significant difference or bias were presented on weighting procedure over time, to check the generated data reliability. This work also exemplifies how control intervals are established.1-4openAccessanalytical solutionmeasuring methodsweightbalancesweight indicatorsquality controlcalibration standardsdiagramsgraph theoryArtigo de periódico01200597510.1088/1742-6596/975/1/012005https://orcid.org/0000-0002-6462-4758Sem Percentil16.00
