Quantitative analysis is classified(according to measurement)

[1] Volumetric (titrimetric) analysis: (Analysis by volume)

Depends on measuring the volume of the analyzed sample and the volume of
standard solution used for complete reaction. This process is known as titration.

[2] Gravimetric analysis: (Analysis by weight)

Depends on weighing the final product of reaction after its isolation in pure and
stable form of definite chemical structure.

[3] Instrumental analysis: (Analysis by instrument)

Depends on measuring physical properties which are quantitatively related to the
analyzed sample, in order to calculate its concentration.

Volumetric analysis is more commonly used as it is more quicker and easier
method if compared with gravimetric and Instrumental methods.
