Most of the researchers employed </span><span lang="EN-GB">liquid chromato­graphy</span><span lang="EN-GB"> (LC) or </span><span lang="EN-GB">gas chromatography (</span><span lang="EN-GB">GC) for determination of MBT. When GC was used, derivatization was necessary in order to prevent decomposition of MBT inside of the hot GC inlet. In this study, a new approach for preventing decomposition of MBT using programmable temperature vaporization (PTV) was presented. The sample was injected in a cold inlet (40 °C) and the tem­pe­rature was raised gradually until the analyte was evaporated. Contrary to hot splitless injection, no decomposition of MBT was observed using PTV. Com­pared to derivatization, PTV requires no chemicals and the duration of analysis is reduced.</span></p> ER -
