This instrument is designed and manufactured in accordance with the requirements specified in the People’s Republic of China standard GB/T11132 “Test Method for Hydrocarbons in Liquid Petroleum Products (Fluorescent Indicator Adsorption Method)”. It is suitable for using fluorescent indicators to display the main hydrocarbons in liquid petroleum products on a silica gel adsorption column in accordance with the method specified in standard GB/T11132, and calculating their volume percentages, which serve as quality determination indicators for fuel oils such as engine fuels and aviation fuels. This instrument is a special-purpose instrument for determining the volume fractions of aromatics, olefins and saturated hydrocarbons in petroleum fractions.
