摘要：
We disclose a device for measuring volatile organic compounds (VOCs) in exhaled breath. The device includes a cover which may be a mask. The cover fits over a user's face as the user breathes. The cover includes one or more removably attached filters which collect VOCs. Some embodiments include reference filters which measure VOCs in the air the user inhales. Reference filter measurements may be subtracted from total VOCs collected from exhaled breath to exclude VOCs that did not originate in the user's body. The filters may be removed from the device and sent for analysis by a gas analyzer which may be a gas chromatograph. Methods of using the device are also disclosed. The device may be used to assess a user's health status, identify or quantify compounds to which a user may have been exposed, or to aid in medical diagnosis.
