A research paper on the differentiation of aspirated nasal air from room air by Jussi Virtanen was published in the Journal of Breath Research!
Nasal air and room air were collected and analyzed using differential ion mobility spectrometry. The dissimilarities between the sample types were studied using statistical methods. The study shows that nasal air is feasible to be collected and subsequently analyzed with DMS. This increases the method’s potential to be used in disease detection.
