Introduction to Analytical Chemistry
- Analytical chemistry focuses on methods and tools for material characterization.
- Fundamental questions addressed: What is it? Where is it found? How much exists? What is its structure?
- Chemical analysis encompasses the chemical characterization of materials.
Definition and Scope
- Defined as the science of chemical measurements.
- Includes methods applied across various fields: industry, medicine, physical and organic chemistry, biotechnology, materials science, manufacturing, and forensics.
Challenges in Analytical Chemistry
- Analytical chemists aim to enhance existing measurement methods.
- Challenges in analyzing metal ions (e.g., Ni2+) in ores include complex matrices and low concentrations.
- Methodology involves dissolving samples, removing interfering elements, isolating target metals, and calculating concentrations.
Practical Applications
- Regular assessments of blood gases (oxygen, carbon dioxide) for medical diagnostics.
- Measurement of pollutants in automotive exhaust for smog control.
- Analysis of ionized calcium for diagnosing parathyroid diseases.
- Nutritional analysis of food for protein content.
- Quality control of steel through monitoring specific elemental concentrations.
Roles of Chemical Analysts
- Analysts apply established techniques for compositional or characterization questions.
- Senior analysts innovate new methods for novel analytical challenges.
- Research analysts develop and study new measurement techniques and fundamental chemical properties.
Analytical Process Steps
- Identify and define the problem.
- Design experimental procedures.
- Conduct experiments and gather data.
- Analyze collected data.
- Propose solutions.
Types of Analytical Questions
- Qualitative analysis: Identifying the presence of substances.
- Quantitative analysis: Determining the concentration of substances.
- Characterization analysis: Evaluating physical and chemical properties.
Common Analytical Techniques
- Qualitative methods: Infrared spectroscopy, Nuclear magnetic resonance, Mass spectrometry.
- Quantitative methods: Gravimetric, volumetric, and electroanalytical methods.
- Gravimetric: Measures mass.
- Volumetric: Measures volume of reacting solutions.
- Electroanalytical: Measures electrical properties.
Analyses Goals
- To solve compositional and characterization issues associated with samples.
- Fundamental analysis aims to improve experimental methods, extending methods’ theory, exploring limitations, and developing new or modified methods.
