Metrology Glossary: Analytical Balance
What Is An Analytical Balance?
An analytical balance serves as a precision weighing tool, specifically designed to determine the mass of small samples with exceptional accuracy and precision. This sophisticated instrument finds its primary application within scientific research, analytical chemistry, and quality control environments, where even the slightest fluctuations in weight yield substantial implications. By employing advanced technology and intricate mechanisms, analytical balances ensure reliable measurements by counteracting external influences such as air currents. Their precision makes them useful for tasks demanding small sample analyses, enabling researchers and professionals to attain dependable results crucial for diverse fields ranging from pharmaceuticals to environmental monitoring.
What Are Analytical Balances Used For?
Analytical balances have many applications within multiple industries including:
- Precision Formulation: Analytical balances play a role in the manufacturing process, precisely weighing ingredients for the production of solutions, compounds, and pharmaceuticals.
- Density Determination: These balances are used to determine the density of both solids and liquids. By accurately measuring the mass and volume of a sample, analytical balances contribute to precise density calculations.
- Interval Weighing for Process Monitoring: Analytical balances facilitate interval weighing, allowing for the continuous measurement of a sample’s mass over time. This application is valuable for monitoring processes such as sample drying or solvent evaporation.
- Accuracy Testing of Micropipettes: The accuracy of micropipettes, essential instruments for dispensing precise liquid volumes, can be verified using analytical balances. This ensures the reliability of these instruments in various laboratory applications.
- Sample Preparation for Instrumental Analysis: Analytical balances are used to prepare samples for analysis in other sophisticated instruments such as spectrophotometers and chromatographs. Precise weighing is crucial for obtaining accurate and reliable results in these analytical techniques.
