ABSTRACT
Chemical analysis of a sample of matter is the determination of the chemical composition of that sample. Chemical analysis consists of a set of chemistry laboratory operations designed to reveal the chemical makeup of a material. Analytical chemistry is a branch of chemistry dealing with the separation and analysis of chemical substances. The results of a chemical analysis could affect important decisions, such as suitability of a material for an intended purpose, the quality of the environment, the health of individuals, and the freedom of a prisoner on trial. The result of a chemical analysis depends on clean glassware. Glassware that looks clean may or may not be clean for chemical analysis. Surfaces on which no visible dirt appears are often contaminated by minute quantities of a substance that interfere with the analysis and give false results. The analyst must carefully read the method and consider any special recommendation for glassware washing procedures.
