Chemical reactions are used to quantify the analyte of interest. Instrumental methods of analysis depend on instruments to carry measurements or to perform the entire analysis. A brief comparison of the classical method (wet chemistry) of analysis versus the instrumental methods is shown in table 2.

instrumental analysis is that magnitude of measured property is proportional to . concentration . of analyte in matrix . Species of interest: All constituents including analyte and Matrix-analyte (concomitants) Often need pretreatment - chemical extraction, distillation, separation, precipitation (A) Classical:
