Wet chemical analysis involves identifying and quantifying the desired elements present in a liquid sample using several methods. It can be divided into two main types, the qualitative analysis identifies the elements and the quantitative analysis determines the quantity. With chemical reagents, the analyte can be used to convert a dye proportionally, which can be read-out visually or photometrically.

The wet chemical analysis comprises a multitude of techniques, including titration, distillation, spectrophotometry (UV/Vis/IR), colorimetry, filtration, drying, weighing, pH tests, and direct read with electrodes. These methods of analysis may be more labor-intensive compared to other methods as automation can’t be applied to some of these techniques.
