A monolithically integrated chromatography device includes a first chromatography column and a second chromatography column formed in a common substrate. The first chromatography column and the second chromatography column are each in fluidic communication with a port formed on the same common substrate. When the port is open, the first chromatography column and the second chromatography column are in fluidic communication with one another. When the port is closed, the first chromatography column and the second chromatography column are not in fluidic communication with one another. The monolithically integrated chromatography device can include a heating element formed on the same substrate as the chromatography columns.

Monolithic multi-dimensional chromatography

A volatile organic compound detection device includes a collector comprising: a collector material configured to collect volatile organic compounds given off from a patient's skin; a heater comprising a heating element, the heating element configured to emit a thermal pulse to desorb the volatile organic compounds from the collector material; and a flow channel configured to receive the volatile organic compounds desorbed by the heater; and a fastener configured to secure the collector to the patient's skin.

Volatile organic compound detection device

The present invention relates to detection systems for detecting an opioid compound by use of pyrolysis, as well as methods thereof. In particular, the systems are configured to detect the presence of a backbone fragment indicative of a class of opioid compounds, including opioid analogues.

Methods and systems for opioid detection

A method of detecting a seizure includes collecting volatile organic compounds with a collector material of a collector; separating a mixture of the volatile organic compounds into its constituent chemicals with a gas chromatography column; ionizing the constituent chemicals to create ionized chemicals and detecting the ionized chemicals; and analyzing the ionized chemicals to identify seizure-indicative volatile organic compounds.

Seizure detection device

Example aspects of a volatile organic compound detection device, a wearable health monitoring device, and a method of monitoring a user's health are disclosed. The volatile organic compound detection device can comprise a collector comprising a collector material configured to collect volatile organic compounds given off from a user's skin; a separator comprising a gas chromatography column configured to separate mixtures of the volatile organic compounds into their constituent chemicals; and an identifier comprising a detector and a processor, the detector configured to transduce the constituent chemicals into a signal, the processor configured to process the signal to identify specific volatile organic compounds indicative of a health condition.

Health monitoring device

A volatile organic compound collector can include a collector material configured to collect volatile organic compounds given off from a patient's skin; a wrapping configured to isolate the collector material from an external environment; a heater comprising a heating element, the heating element configured to emit a thermal pulse to desorb the volatile organic compounds from the collector material; and a mesh layer configured to prevent the collector material from contacting the patient's skin, wherein the collector material is received between the wrapping and the mesh layer.

The present invention relates to functionalized polymers useful for coating surfaces, such as the internal bore of a column. In particular embodiments, such functionalized polymers provide a selective stationary phase useful for separating and detecting organophosphorous agents. Methods of using such polymers are also described herein.

Functionalized coating polymers and uses thereof

Example aspects of a collector for a seizure detection device, a seizure detection device, and a method of detecting a seizure are disclosed. The collector for a seizure detection device can comprise a collector material configured to collect volatile organic compounds given off from a patient's skin; a wrapping configured to isolate the collector material from an external environment; a heater comprising a heating element, the heating element configured to emit a thermal pulse to desorb the volatile organic compounds from the collector material; and a mesh layer configured to prevent the collector material from contacting the patient's skin, wherein the collector material is received between the wrapping and the mesh layer.
