Study Notes
Analytical Chemistry
- Analytical chemistry is the discipline that involves the use of different methods and tools to determine and measure the chemical composition of any given sample.
Types of Analysis
- Qualitative analysis: Identifying the components of a sample, e.g., identifying the presence of a particular element or compound.
- Quantitative analysis: Measuring the exact amount of a component in a sample.
Bioanalysis
- Bioanalysis: The qualitative and quantitative analysis of biological samples in biology and biochemistry, e.g., analyzing blood or tissue samples for disease diagnosis.
Old Classical Analytical Methods
- Examples of old classical analytical methods include: Titration, Gravimetry, and Chromatography.
Identification of Chemicals
- Qualitative identification: Identifying chemicals and molecules in a given sample without measuring the exact amount.
- Quantitative identification: Identifying chemicals and molecules in a given sample with the exact amount.
Bioanalysis Examples
- Bioanalysis in biology and biochemistry involves the analysis of biological fluids, tissues, and other samples to diagnose diseases, monitor therapy, and understand biological processes.
Old Laboratory Methods
- Examples of old laboratory methods include: Crystallization, Distillation, and Electrophoresis.
