Abstract
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.
Claims20
A portable system configured to collect a sample from exhaled breath of a subject, and for detecting the presence or determining the quantitative amount of at least one drug substance in said exhaled breath,
- said system being adapted to collect said sample for further analysis using mass-spectroscopy, said system comprising:
- a sampling unit and a housing arranged to hold said sampling unit,
- said sampling unit is adapted to collect at least one of non-volatile and volatile compounds of said at least one drug substance from said exhaled breath from said subject;
- and
- wherein said housing comprises at least one inlet for said subject to exhale into said housing to said sampling unit and at least one outlet for said exhaled breath to exit through.
A method for portably collecting a sample from exhaled breath of a subject, and for detecting the presence or determining the quantitative amount of at least one drug substance in said exhaled breath, said method comprising:
- collecting said sample comprising at least one of a non-volatile or volatile compound from said subject, using a system comprising a sampling unit and a housing arranged to hold said sampling unit, wherein said sampling unit is adapted to collect at least one of non-volatile and volatile compounds of said at least one drug substance from said exhaled breath from said subject, and in said housing comprises at least one inlet for said subject to exhale into said housing to said sampling unit and at least one outlet for said exhaled breath to exit through;
- and
- analyzing said collected sample using mass-spectroscopy.
