摘要： A high speed liquid chromatography to separate hydrocarbon compounds contained in a solution into three components, namely, saturates, unsaturates and aromatics, an analytical method of hydrocarbons which comprises(a) using an organic chlorine-containing type solvent or a mixed solvent of an organic chlorine-containing type solvent and a hydrocarbon type solvent as an eluent;(b) connecting the first column into which a silica type packing material is packed and the second column into which a silver-containing silica type packing material is packed in series; and(c) introducing the eluate from the second column to a detector to detect it quantitatively.

摘要： Disclosed are a closed heat-decomposing appliance comprising a heating section with one side closed and other side having common ground portion, screw portion or O-ring-mounted portion and a closed introducing section that allows to connect to this heating section and common ground portion, screw portion or O-ring via O-ring-mounted portion and has cock or valve as a mechanism for closing and introducing the absorbing liquid to absorb the testing components from outside after heat-decomposition, or has packing or septum to introduce the absorbing liquid with needle pipe as well, and a pretreatment method of sample using this appliance. The purpose is to provide a closed heat-decomposing appliance for the pretreatment on accurate quantitative determination or detection of the testing components in sample, which requires no combustion assistant, which is not obstructed by ash present in sample absorbing the testing components, which requires no complicated and dangerous procedures, which can be used repeatedly, and which allows to inject the absorbing liquid after heat-decomposition, and a pretreatment method using it.
