Analytical Chemistry is the method that is used to separate, identify, and quantify the matter. All these processes may constitute the entire analysis or to be combined with another method. The separation process is isolating the analytes. The qualitative analysis process identifies the analytes and quantitative analysis identifies the numerical amount or concentration.
Analytical chemistry is having two methods i.e., classical or wet chemical methods and modern, instrumental methods. Classical qualitative methods used for separating are precipitation, extraction and distillation. Identification depends on color, odor, melting point, boiling point, solubility, radioactivity also uses mass or volume changes. Instrumental methods used to separate samples are chromatography and electrophoresis. Then qualitative and quantitative analysis can be done under the same instrument or may use light interaction, heat interaction and electric fields. These whole methods describe the analysis process, where separation isolates the analytes. Quantitative analysis identifies the numeric amount or concentration of the solutes, where the qualitative identifies the analyses.
Bio analytical chemistry is covering the quantitative measurements like xenobiotic and biotic. Drugs, biological molecules undergo xenobiotic method and protein, DNA, large molecules of drugs undergo biotic. Some techniques are commonly used in bio analytical studies. They are as follows;
