Review of Chemical Fingerprinting Analysis

Abstract

A specific pattern that can be used to detect a contaminant, medication, toxin, or even other substance in a lab test using specialist analytical methods like mass spectroscopy or X-ray spectroscopy. Iodine, cyanoacrylate, silver nitrate, and ninhydrin are the four main compounds forensic scientists use to identify and gather fingerprints. These compounds cause the fingerprint to change color in response to components in the print, such as sweat and oil, making it easier for analysts to read. For the quality control, a quick and trustworthy HPLC fingerprinting method was created and approved. By methodically comparing chromatograms using specialized analytical tools, the viability, and benefits of the employed HPLC fingerprint were confirmed for its similarity evaluation. Fingerprinting analysis revealed many types of results. The outcomes showed that the HPLC fingerprint can be successfully used to evaluate the quality and to identify as a distinctive differentiating technique integrating similar assessment and quantitative analysis. The term “chemical fingerprinting” refers to a group of methods that use a sample’s chemical makeup to determine where it came from
(including a contaminant). Petroleum biomarkers are commonly utilized for this in geochemical and forensic oil spill identification. For the quantitative analysis of five active chemicals as well as chemical fingerprint characterization, a procedure based on ultra-performance liquid chromatography with a diode array detector was devised. By methodically comparing chromatograms with the advised analytical software, the viability, and benefits of the applied UPLC fingerprint were confirmed for its similarity evaluation.
