1.16 | chemical purity | ||

purity | |||

Mass (amount of substance or number of entities) of a specified component divided by the mass (amount of substance or number of entities, respectively) of the system. | |||

Note 1: | Purity is usually related to a major component. The other components are termed “impurities”. | ||

Note 2: | The quantity, component and system must be specified. | ||

Note 3: | The numerical quantity value of purity is often expressed as per cent or per mille. | ||

Note 4: | Purity can be measured as where f_{j} denotes fractions of the same type (mass fraction, amount of substance fraction or number fraction) of all other known components j = 1,…, N. If the contributions are expressed as mass fractions, this estimation is sometimes termed “mass balance”. |
