This constitutes the chromatographic profile of the essential oil.Important Due to the viscosity of this essential oil, it is necessary to dilute it with 1,8
28、cineole so that the final mass fraction of each component in the mixture is 50 %. It is also recommended to use a polyethylene glycol type polar column. There will be two integrations, with and without 1,8-cineole.2 ISO 2013 All rights reservedBS ISO 4716:2013ISO 4716:2013(E)Table 1 Chromatographic

48、sport companies, insurance companies, and people in charge of safety services require information on the flashpoints of essential oils, which in most cases are flammable products.A comparative study on the relevant methods of analysis (see ISO/TR 110181) concluded that it was difficult to recommend
49、a single apparatus for standardization purposes, given that: there is a wide variation in the chemical composition of essential oils; the volume of the sample needed in certain requirements would be too costly for high-priced essential oils; as there are several different types of equipment which can be used for the determination, users cannot be expected to use one specified type only.Consequently, it was decided to give a
