General steps in chemical analysis
Identify the problem & formulate the question
Analytical method selection
wet chemical methods
Gravimetric analysis
Volumetric analysis
instrumental methods
Chroatographic analysis
Measure peak areas of separated components of a sample
Spectroscopic analysis
Measure interaction between analyte and electromagnetic radiation
Electroanalytical analysis
Measure an electrical property which is chemically related to the amount of analyte
Sampling, sample preservation, and sample preparation
A process to get a representative & homogenous sample
Types of sampling
Liquid
Gas
Solid
Transported the sample to the analytical laboratory without ANY physical or chemical change.
Preservation helps minimize physical changes & chemical changes.
sample preparation analysis
Brought the sample into correct size/form
Consolidation of findings & reporting
Use of statistical methods
Results with accuracy & precision
