The high brightness (surpassing synchrotron) and ultra-broad spectral bandwidth (2\u20134 \u03bcm) of this light source allows simultaneous detection of multiple broadband absorbing gas species. High sensitivity in the sub-ppmv level has been achieved by utilizing an astigmatic multipass cell. A grating-based spectrometer at a scanning rate of 20 Hz is developed employing a balanced detection scheme. A multi-component global fitting algorithm is implemented into a central LabVIEW program to perform real-time data analysis. The obtained concentration values are validated by the standard gas chromatography mass spectrometry (GC-MS) method. Field application of the sensor for quality control of stored fruits at a small scale is demonstrated, involving the detection of ethylene, ethanol, ethyl acetate, acetaldehyde, methanol, acetone, and water simultaneously. The sensor also shows promising potentials for other applications, such as environmental monitoring and biomedical research.<\/jats:p>","DOI":"10.3390\/s19102334","type":"journal-article","created":{"date-parts":[[2019,5,21]],"date-time":"2019-05-21T10:52:51Z","timestamp":1558435971000},"page":"2334","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["A Broadband Mid-Infrared Trace Gas Sensor Using Supercontinuum Light Source: Applications for Real-Time Quality Control for Fruit Storage"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4455-098X","authenticated-orcid":false,"given":"Khalil","family":"Eslami Jahromi","sequence":"first","affiliation":[{"name":"Trace Gas Research Group, Institute of Molecules and Materials, Radboud University, 6525 AJ Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qing","family":"Pan","sequence":"additional","affiliation":[{"name":"Trace Gas Research Group, Institute of Molecules and Materials, Radboud University, 6525 AJ Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amir","family":"Khodabakhsh","sequence":"additional","affiliation":[{"name":"Trace Gas Research Group, Institute of Molecules and Materials, Radboud University, 6525 AJ Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cor","family":"Sikkens","sequence":"additional","affiliation":[{"name":"Trace Gas Research Group, Institute of Molecules and Materials, Radboud University, 6525 AJ Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Assman","sequence":"additional","affiliation":[{"name":"Trace Gas Research Group, Institute of Molecules and Materials, Radboud University, 6525 AJ Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simona M.","family":"Cristescu","sequence":"additional","affiliation":[{"name":"Trace Gas Research Group, Institute of Molecules and Materials, Radboud University, 6525 AJ Nijmegen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter M.","family":"Moselund","sequence":"additional","affiliation":[{"name":"NKT Photonics A\/S, Blokken 84, DK-3460 Birkeroed, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maxime","family":"Janssens","sequence":"additional","affiliation":[{"name":"Flanders Center of Postharvest Technology, Willem de Croylaan 42, 3001 Heverlee, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bert E.","family":"Verlinden","sequence":"additional","affiliation":[{"name":"Flanders Center of Postharvest Technology, Willem de Croylaan 42, 3001 Heverlee, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6192-3322","authenticated-orcid":false,"given":"Frans J.
