Abstract
A system, method, and device for analyzing a sample using spectroscopy. The system includes a spectroscope, a sample vial with a swab removably sealable within a transparent enclosure, the swab including an absorbent collection substrate. The system further includes a sample vial adaptor configured to affix to the spectroscope, and a sample vial receptacle that receives the sample vial. The adaptor is configured to position the sample vial such that the transparent portion of the enclosure is between the swab and the laser of the Raman instrument, and such that the swab is positioned at the focal distance of the laser.
