The reason for the usage of splitless injection in purge and trap preparation of sample has to be explained. Concept Introduction: Purge and trap: The removal of volatile analytes from solids or liquids, concentrating the analytes and using in the gas chromatography is called as Purge and trap. The removal of 100% of analyte from the sample is achievable by purge and trap. The removal of polar analytes in quantitative way from polar matrices could be tedious process in purge and trap. Splitless injection: Splitless injection is necessary for solutions in very dilute form. Splitless injection is most suitable for analyte with high concentration. They offer poor quantitative analysis and compounds with less volatile nature could be lost during injection. Splitless injection is better than split injection for compounds that have moderate thermal stability because the injection temperature would be lower. Since the sample is injected slowly, solvent trapping and temperature programming is required. To explain the reason for the usage of splitless injection in purge and trap preparation of sample
