Detailed explanation-1: -An analysis provides chemical or physical information about a sample. The component in the sample of interest to us is called the analyte, and the remainder of the sample is the matrix. In an analysis we determine the identity, the concentration, or the properties of an analyte.

Detailed explanation-2: -These are the tests performed for the determination of the characteristics such as colour, odour, appearance, pH, density and viscosity.

Detailed explanation-3: -According to International Union of Pure and Applied Chemistry (IUPAC) a sample is defined as a portion of material selected from a larger quantity of material. Sampling is defined as the total of activities that end with the acquisition of the test portion (actual subject of analysis).

Detailed explanation-4: -A technique is any chemical or physical principle that we can use to study an analyte. There are many techniques for that we can use to determine the concentration of lead in drinking water [Fitch, A.; Wang, Y.; Mellican, S.; Macha, S. Anal.

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.
