Detailed explanation-2: -A calibration is the process of experimentally determining the value of kA by measuring the signal for one or more standard samples, each of which contains a known concentration of analyte.

Detailed explanation-3: -chemical analysis, chemistry, determination of the physical properties or chemical composition of samples of matter.

Detailed explanation-4: -Method validation is a procedure of performing numerous assessments designed to verify that an analytical test system is suitable for its intended reason and is capable of providing beneficial and legitimate analytical data [4, 5, 6, 7, 8].

Detailed explanation-5: -What Is Analytical Method Validation? Analytical method validation establishes documented evidence that the procedure adopted for a test is fit for the intended purpose in terms of quality, reliability and consistency of results.
