Chemical metrology.

Area of Science:

• Analytical Chemistry
• Metrology
• Measurement Science

Background:

• Chemical metrology often causes confusion among analytical chemists.
• Metrology, the science of measurement, has ancient roots and was formalized for physical sciences in the late 19th century.
• Global adoption of metrology principles extended to analytical chemistry in the late 20th century.

Purpose of the Study:

• To clarify the principles and value of metrology in chemical measurements.
• To demystify the concept of chemical metrology.
• To highlight the historical development and current implementation of metrology in chemistry.

Main Methods:

• Historical review of metrology principles.
• Explanation of the formalization of metrology for physical measurements.
• Description of the extension and implementation of metrology in analytical and biological sciences.

Main Results:

• Metrology's fundamental principles ensure consistency in measurements.
• The application of metrology has evolved from ancient times to modern scientific disciplines.
• An international infrastructure for chemical and biological measurements is progressing.

Conclusions:

• Chemical metrology is essential for reliable and consistent chemical analysis.
• Understanding metrology's principles enhances the quality of chemical measurements.
• The global integration of metrology into chemistry and biology is advancing.
