Present invention in general concerns a system and an apparatus to accelerate oxidation chemistry of sample of organic products by non-thermal plasma based on variability due to the difference of the physico-chemical properties of the organic samples to be tested. More particularly the non-thermal plasma system or non-thermal plasma apparatus comprises at least one enclosure for connecting or removing sample holders so that the apparatus can comprise at the position under the NTP comprise different types of sample holders and preferably it comprises such enclosures to hold a plurality of sample holders. Preferably this sample holder is functionally connected with a motor so that separate sample holders can be moved under the non-thermal plasma (NTP) discharge and so that the sample position of the sample holder is controllable. This is system and an apparatus functionally connected with a volatile trap in such a way that a volatiles released from said the composition it is trapped. The sample holder can comprises an attachment means or an enclosure on top so that it can be covered by a NTP penetrable mesh. In a specific embodiment the trap is connected to or followed by a VOC analyser, for instance a VOC analyzer that comprises detectors of the group consisting of an electronic nose, FID, MS, UV, IR, TOF and SIFT-MS.
