Q5:What is the correction factor indicated in the accompanying leaflet of a reference standard?
A5: As a general rule, the reference standards are regarded as being 100.0% pure for the official use in quantitative applications (for reference, please see A4). However, some reference standards are indicated the correction factors based on their purity determined by using the mass balance approach considering their official use(s) in the quantitative applications, respectively. When a correction factor for the purity is indicated in the accompanying leaflet, the weighed amount of the reference standard must be corrected using the correction factor. Each lot of a reference standard, which is distinguished by ‘Control Number’, could have a different correction factor. Thus, please check the accompanying leaflet for each lot of a reference standard.
