A portable system is disclosed for collecting a sample from exhaled breath of a subject. Drug substance in the exhaled breath are detected or determined. The sample is collected for further analysis using mass-spectroscopy. The system comprises a sampling unit and a housing arranged to hold the sampling unit, the sampling unit is adapted to collect non-volatile and volatile compounds of the at least one drug substance from the exhaled breath from the subject. The housing has at least one inlet for the subject to exhale into the housing to the sampling unit and at least one outlet for the exhaled breath to exit through.

System and method for drug detection in exhaled breath

A portable system () is disclosed for collecting a sample from exhaled breath of a subject. Drug substance in the exhaled breath are detected or determined. The sample is collected for further analysis using mass-spectroscopy. The system comprises a sampling unit () and a housing () arranged to hold the sampling unit (), the sampling unit () is adapted to collect non-volatile and volatile compounds of the at least one drug substance from the exhaled breath from the subject. The housing () has at least one inlet () for the subject to exhale into the housing () to the sampling unit () and at least one outlet () for the exhaled breath to exit through.

A device, system, and methods are disclosed for detecting the presence or determining a quantitative amount of at least one drug substance from exhaled breath of a subject in-situ. A collecting surface has a Surface Enhanced Raman Spectroscopy (SERS)-active layer that comprises at least one SERS-active material. The collecting surface is arranged as an outer surface of a waveguide for contact with exhaled breath, such that at least traces of said at least one drug substance in said exhaled breath can contact said SERS-active layer for read-out of a Raman shift spectrum that is detected in-situ for said detecting the presence or determining the quantitative amount of said at least one drug substance from said exhaled breath.

System and method for detection of analytes in exhaled breath

A sensor for detecting a drug substance () from exhaled breath of a subject in-situ. Its collecting surface has a Surface Enhanced Raman Spectroscopy (SERS)-active layer () of a SERS-active material. The collecting surface is arranged as an outer surface of a waveguide () for contact with exhaled breath, such that at least traces of said drug substance () in said exhaled breath can contact said SERS-active layer for read-out of a Raman shift spectrum.

The present invention is related to a method and device for precision and passive alignment such as precision and passive alignment technology for low cost array fibre access components. A laser carrier is passively aligned to an MT-interface using alignment structures on a replicated carrier. The laser carrier is based on a self-aligned semiconductor laser, flip-chip mounted on a silicon substrate with planar polymeric waveguides.
