Description

The present invention relates to a collection container used for collecting volatile oils at the time of identification activities, and a method for collecting volatile oils at the time of identification activities.

The present invention has been proposed in order to solve the above-described problems of the prior art. A container that can be stored for a long time without losing and contaminating the collected volatile oil, and a volatile oil The purpose is to provide a collection method .

The collection container of the present invention includes a bottle having an open top surface, a cap that seals the opening and has a hole portion on the top surface, and the hole portion is sealed with a partition wall member that can be punctured with a collection needle, An adsorbent that adsorbs volatile oils and can be taken in and out of the bottle.
In the method for collecting volatile oils of the present invention, an adsorbent that adsorbs volatile oils to be identified is stored in advance in a collection container whose upper surface is opened, and the upper surface opening of the collection container is sealed with a cap. In addition, at the time of collection, remove the cap of the collection container and take out the adsorbent inside the container, soak the organic solvent to the adsorbent, then wipe off the volatile oil by the adsorbent, The adsorbent from which volatile oils have been wiped is stored in the collection container, and the opening is sealed.
