    Abstract: A specimen collection receptacle formed by a channel disposed within the wall of a toilet bowl. The receptacle is located above the weir water line. The receptacle comprises a channel open to the interior of the bowl having opposed non-parallel side walls. The side walls may be joined opposite the opening. The side walls may be joined by a bottom wall. The bottom wall may be arcuate. The side walls may be non-planar. The walls may exhibit a roughened surface. The receptacle may comprise an optical window. The receptacle may comprise a cuvette. The receptacle may be in communication with one or more light emitting probes. The receptacle may be self-cleaning. The receptacle may comprise a replaceable module disposed in the wall of the toilet bowl. The receptacle may be located at the front of the toilet bowl. The receptacle may be disposed in a toilet bowl liner or insert.

    Abstract: We disclose an in-toilet urinalysis system which includes a system for collection urine and applying the urine to a urine test strip. The system may include an orifice within a toilet bowl which leads into a channel. The channel may be connected to a capillary which has an orifice at each end. Urine may pass through the orifice, into the channel, then may be moved by capillary action through the capillary. A urine test strip dispenser may move reaction pads on a urine test strip to the distal end of the capillary to load the reaction pads with urine. The reaction pads may absorb the urine from the most distal orifice of the capillary. A measurable chemical reaction may occur in the reaction pads in response to urine analytes.

    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.
