摘要
Method for the identification of a lubricating oil composition, characterised in that it comprises the following steps: a heating process to heat the lubricating oil composition which is the target of the investigation and which has the possibility of containing a volatile amine as a marker; after the heating process, a first reaction process which disposes into a vapour phase on top of the liquid surface of the lubricating oil composition a medium which contains an amine colouring reagent to be used in at least one kind of amine-based colouring reaction selected from a group comprised of quinhydrone reactions, ninhydrin reactions and Dragendorff reactions; after the heating process, a second reaction process which disposes into a vapour phase on top of the liquid surface of the lubricating oil composition a medium which contains a pH-dependent colouring reagent to be used in a pH-dependent colouring reaction; and an evaluation process in which the lubricating oil composition which is the target of the investigation is assessed as to whether or not it is a specific lubricating oil composition by at least comparing a standard colouring pattern, in which a first colouring pattern attributable to the reaction or non-reaction of an amine colouring reagent and a volatile amine and a second colouring pattern attributable to the reaction or non-reaction of a pH-dependent colouring reagent and a volatile amine are displayed, with a colouring pattern which is the result of the first reaction process and the second reaction process.
