Breath condensate and saliva analysis using oral rinse

A system comprising:

• a sample extraction device including a sorbent;
• a sample vial containing a sample, the sample prepared in a method comprising:
• rinsing a mouth of a subject with an inert liquid to combine the inert liquid with one or more of saliva and breath condensate;
• and
• depositing the combination of the inert liquid and the one or more of the saliva and breath condensate into the sample vial;
• coupling a sample extraction device to the sample vial, wherein coupling the sample extraction device to the sample vial seals the sample vial from an environment of the sample vial, and the sample extraction device includes a sorbent;
• coupling a vacuum source to the sample extraction device;
• drawing a vacuum, with the vacuum source, in the sample vial through the sample extraction device for a first period of time, such that in the process of drawing the vacuum, the vacuum is drawn through the sorbent included in the sample extraction device;
• cease drawing the vacuum in the sample vial;
• after ceasing to draw the vacuum in the sample vial and while the vacuum is held in the sample vial, extracting, from the combination of the inert liquid and the one or more of the saliva and breath condensate, one or more volatile or semi-volatile compounds of the sample from the sample vial;
• and
• collecting the one or more volatile or semi-volatile compounds of the sample in the sorbent of the sample extraction device, and
• a chemical analysis device configured to perform a chemical analysis of the one or more volatile or semi-volatile compounds of the sample.
