Detailed explanation-1: -A method is the application of a technique to a specific analyte in a specific matrix.

Detailed explanation-2: -Selectivity/specificity. Selectivity of an analytical method is its ability to measure accurately an analyte in the presence of interferences that may be expected to be present in the sample matrix.

Detailed explanation-3: -analyte: the substance that is of interest in the analysis (for example: amount of hemoglobin in blood); matrix: the constituents, apart from the analyte, of the given sample (for example: all the constituents of blood except hemoglobin);

Detailed explanation-4: -Colorimetric analysis is the technique normally used to determine the concentration of analyte through comparing the color changes of the solution.

Detailed explanation-5: -Analytical chemistry methods refer to techniques used for the detection, identification, characterization, and quantification of chemical compounds. These methods are commonly used in biology for research, development, and quality control of pharmaceutical products.
