Abstract: We disclose a medical toilet that includes a system for interpreting measurements collected by medical devices on or in the medical toilet and for customizing the measurements to each user. The system may use information about the user to selecting which measurements to perform, select or modify parameters that apply to the measurement techniques, and select follow-up measurements that may be performed based on the first set of measurements. These decisions may be made according to the user's physical, demographic, or medical status information that may be entered into a controller connected to the medical toilet. The controller may apply a set of rules to the measurements and thereby determine a value which provides an estimate of the validity of the measurements and which may be used to make adjustments to subsequent measurements.

Abstract: We disclose a method of tagging nutritional or drug compositions using chemical entities which are known to be safely consumed and which are detectable using known techniques, including near IR spectroscopy. The chemical entities used as tags may be detected in easily obtainable biological samples, including urine and feces. The biological sample may be deposited into a medical toilet which may analyze the biological sample using an analytical device associated with the medical toilet. The tag may be identified and quantified to then identify and quantify the nutritional or drug composition the subject consumed along with the tag. This system may be used to track the source of a food or drug, confirm compliance to a prescribed diet or drug treatment, confirm drug consumption in clinical trials, identify the source of contaminated food, and identify the food substances used to produce food products.

Abstract: We disclose a method of using taggants to assess how and to what extent a drug in a drug composition that a user has consumed has decayed in response to storage conditions and time. The taggants may decay in response to environmental conditions which cause different drugs to lose their efficacy. These environmental conditions may include light, temperature, oxidation, and age. The taggants may be detected in biological samples, including urine and feces. By identifying the taggants, the drug composition and other information relating to the drug may be identified. Additionally, quantification of the different taggants may be used to determine whether the drug in the drug composition has been exposed to environmental conditions which may reduce its efficacy.

Abstract: We disclose a microfabricated device for both extracting and preconcentrating samples for gas chromatography analysis. The device includes a conduit with at least two sections and multiple ports which may be connected to multiple gas chromatography columns. The inner surface of the conduit may be coated with multiple sorbents which bind volatile analytes with different affinities. The sections of the conduit may be divided by a thermal barrier which inhibits heat transfer between sections. Consequently, each section may be independently heated to encourage desorption of volatile analytes. The disclosed device separates and concentrates volatile analytes into different pools according to their chemical and physical properties before they enter a gas chromatography column that is optimized for that pool. The device reduces the amount of heat and time needed to perform gas chromatography analysis as well as avoids the need for purified gas sources typically used for the moving phase.

Abstract: The tandem differential mobility spectrometer (DMS)-ion modulator instrument provides improved resolution relative to traditional DMS for molecules with larger masses. The instrument includes multiple ion-bunching electrodes, each with an AC field synchronized to the transit time of the ion flow which is positioned downstream of a DMS. The ion bunching electrodes produce each a mobility-dependent modulation of the ion current. The ratio of AC to DC current provides a measure of the mobility of a large ion, even if it has little differential mobility, thereby extending the useful range of mobility characterization of a DMS system. The instrument does not require high voltages or high frequencies. Modulation before DMS separation or between tandem DMS separations produces a variable range of analyte and reactant ion densities as well as spatially separating negative and positive ions to reduce ion recombination.
