There are many types of literature review and the following types of literature review are the most popular in business studies: Narrative literature review critiques the literature and summarizes the body of a literature. Many of the methods can be used for both qualitative and quantitative analysis. Qualitative instrumental analysis is that measured property indicates presence of analyte in matrix Quantitative instrumental analysis is that magnitude of measured property is proportional to concentration of analyte in matrix 2Instrumental analysis CHOOSING AN ANALYTICAL METHOD If two spectra match, they must be from the same metal ion. is the pair of electrodes and the air between them. Electrochemical methods of analysis, in which the analyte participates in a redox reaction or other process. Instrumental analysis.
