Meaning
Instrumental Chemical Analysis is the use of measuring instruments to identify chemicals.
About Instrumental Chemical Analysis
- Flame Tests, Gas Tests, aqueous ion tests testing for lipids, glucose, starch and proteins all rely on humans observing a reaction which can be flawed because humans make mistakes.
- Instrumental Chemical Analysis does not rely on humans to make observations. Instead the instruments are used to give more accurate and precise observations. They are also often much quicker than a human could do it.
- Such instrumental chemical analysis is performed in airports when testing for drugs or explosives, in hospital when testing for diseases.
- Flame Emission Spectroscopy is an example of instrumental chemical analysis.
