Ultimate analysis
utilizes data from observing chemical reactions to determine the quantitative and qualitative property of a sample
Examples: Gravimetric analysis, titration and bioassays
Chemical procedure or Classical method
utilizes data from observing the physical chemical properties of the sample using quantitative instruments
– The data from this method were gathered based on the measurements of certain chemical and physical attribute of a sample.
Example: Spectrometry-absorbance; refractometer-refractive index; polarimeter-angle of rotation of light
Instrumental Method
assay of biological activity and of certain natural products, which includes chemical, biological, genomics and microbiological methods
