Here’s a explanation:
Role of Chemical Sensors in Analytical Chemistry
- Detection of Substances
- Chemical sensors can detect specific chemicals or ions in a sample.
- Example: Detecting glucose in blood.
- Real-Time Monitoring
- They provide instant measurements, useful for continuous monitoring.
- Example: Monitoring air quality or pollution levels in real time.
- High Sensitivity and Selectivity
- Sensitive to small amounts (high sensitivity).
- Respond mainly to the target substance (high specificity).
- Portable and Convenient
- Many sensors are small and easy to use, allowing field testing.
- Example: Portable pH meters or gas sensors.
- Automation and Integration
- Can be integrated with electronic systems for automated data collection and analysis.
Simple way to remember:
Chemical sensors are like smart detectors: they find, measure, and report chemicals quickly and accurately.
