Study Notes
Medical Instrumentation
- Medical devices are a fundamental component of health systems, essential for preventing, diagnosing, and treating illnesses and diseases in a safe and effective way.
Optical Techniques
- Based on the interaction between electromagnetic radiation (light) and analyte (sample)
- Energy can be emitted, transmitted, absorbed, or scattered/ reflected
- Types of optical techniques include:
- Spectral
- Atomic
- Fluoro
- Chemical
- Turbid
- Nephelo
Electromagnetic Waves
- Created by vibrating electric charges
- Can travel through a vacuum (no medium needed)
- Have a wide range of frequencies and wavelengths
- People can only see wavelengths around 400-700 nanometers
- Travel at the speed of light in a vacuum (300,000 km/s or 670,617,000 mi/hr)
Electromagnetic Spectrum
- Divided into the following regions:
- Cosmic Rays
- Gamma Rays
- X-rays
- Ultraviolet Rays
- Visible Light
- Infrared Rays
- Microwaves
- Radio Waves
Optical Methods
- Based on the interaction between electromagnetic radiation and sample
- Include the following techniques:
- Spectrophotometry
- Atomic absorption spectrophotometry
- Fluorometry
- Chemiluminescence
