What is Chemical Analysis? Gas Chromatography/Mass Spectrometry is used to qualitatively identify unknown materials by comparing a sample’s mass spectrum to a large reference library of spectra. GC/MS analysis is also used quantitatively to determine the concentration of the components within a sample.Click to see full answer. Similarly, what is the purpose of chemical analysis?chemical analysis, the study of the chemical composition and structure of substances. The procedures by which these aims may be achieved include testing for the chemical reaction of a putative constituent with an admixed reagent or for some well-defined physical property of the putative constituent.Likewise, how is chemical analysis done? The main steps that are performed during a chemical analysis are the following: (1) sampling, (2) field sample pretreatment, (3) laboratory treatment, (4) laboratory assay, (5) calculations, and (6) results presentation. Each must be executed correctly in order for the analytical result to be accurate. Then, what are the types of chemical analysis? Chemical methods depend upon such reactions as precipitation, neutralization, oxidation, or, in general, the formation of a new compound. The major types of strictly chemical methods are known as gravimetric analysis (q.v.) and volumetric, or titrimetric, analysis (see volumetric analysis).What is a chemical sample?chem·i·cal sam·pling. a sample that is obtained by whatever means is convenient and then purified of irrelevant elements before analysis; the assumption of thorough mixing is not necessary.
