1.Qualitative Analysis

  • Identifies the presence of elements, ions, or compounds in a sample.
  • Does not determine the quantity.
  • Example techniques:
  • Flame tests (for metal ions).
  • Spot tests (specific color reactions).
  • Spectroscopic methods (e.g., UV-Vis, IR spectroscopy).

2. Quantitative Analysis

  • Measures the exact amount or concentration of a substance in a sample.
  • Techniques include:
  • Gravimetric Analysis: Measuring mass.
  • Titrimetric Analysis: Using titration to determine concentration.
  • Instrumental Techniques:
  • Chromatography (e.g., Gas Chromatography, HPLC).
  • Mass Spectrometry (MS).
  • Atomic Absorption Spectroscopy (AAS).
  • NMR Spectroscopy.

3.Applications of Chemical Analysis

  • Industrial Quality Control: Ensuring products meet specifications.
  • Environmental Monitoring: Measuring pollutants in air, water, and soil.
  • Pharmaceutical Industry: Analyzing drug purity and formulation.
  • Forensics: Identifying substances in crime investigations.
  • Research and Development: Studying new materials or chemical reactions.

4. Techniques of Sampling in Chemical Analysis

  • Definition: Sampling is the process of selecting a representative portion of a material for analysis.
  • Importance: Ensures accuracy and reliability of results.
  • Random Sampling: Collecting samples at random locations.
  • Systematic Sampling: Following a fixed pattern or interval.
  • Composite Sampling: Mixing multiple samples to create an average.
  • Grab Sampling: A single, specific point in time or location.
