Chemical analysis refers to the study of the chemical composition and structure of substances. It is divided into two categories, which include qualitative and quantitative analysis. Qualitative analysis is used for determining whether or not a substance is present in a sample. Quantitative analysis is utilized to determine the amount of a substance present in a sample. Chemical analysis studies the chemical components of a material which aids in the identification of unknown materials or the verification that the material satisfies the necessary conditions. The key steps performed during chemical analysis include sampling, field sample pretreatment, laboratory treatment, laboratory assay, calculations and results presentation. Chemical analysis is critical for ensuring the chemical's productivity, safety, consistency, quality and control. This book explores all the important aspects of chemical analysis in the present day scenario. It is appropriate for students seeking detailed information in this area of chemistry as well as for experts.
