A container cap liner that that facilitates the storage of gases and various volatile organic compounds (VOCs). More particularly, the container cap liner reduces the loss of gases and various volatile compounds thereby providing for relatively longer storage periods with relatively more accurate analytical analysis.

The present invention provides a device and process that rapidly assesses volatile organic compounds (VOCs) present in a gaseous state by reading gas emitted through a subject's skin into the ambient surroundings. The device delivers rapid high-sensitivity capture, classification and pattern recognition to identify a unique VOC profile derived from that bio-sample. A flexible probe module can be appropriately configured with attachments to collect gases from the air surrounding any person, any area enclosed or proximal to a potential VOC source, and/or in clinical applications, near any skin surface, from zones or areas within or immediate adjacent to a body orifice such as nasal passage, otic canal, mouth, armpit, vagina, urethra, navel, anus, vagina, scalp, torso, palm, foot, etc. The device thus provides a practical screening device for clearing persons of interest, e.g., in a waiting room, planning to enter a room or building, a client seeking a personal meeting, etc., and/or providing a handyman, health care worker, or other service provider, a means of assurance when entering a place of service.

A testing assembly for the rapid detection of a desired chemical from a sample, the testing assembly having a sample collection device for obtaining the sample and depositing the sample into a chemical capture cartridge that operably engages with a sensing device, the chemical capture cartridge utilizing the microdiffusion of reagents to isolate the desired chemical from the sample and react the desired chemical to form a detectible complex that can be detected and measured. The testing assembly can be portable and can rapidly diagnose a toxic industrial chemical exposure in just a few minutes, preferably about a minute or less for cyanide exposure using a blood sample from a subject onsite. The testing assembly can be used to determine the presence and/or concentration of a toxic industrial chemical in a variety of samples, including biological, environmental, and industrial samples.

Methods and systems for capture of CO.sub.2 from a hydrated gaseous stream are described. Systems can be utilized for direct air capture of CO.sub.2 and incorporate a low energy temperature-vacuum swing adsorption (TVSA) process. A TVSA process can include a multi-step CO.sub.2 capture bed regeneration process that includes depressurization of the bed, heating of the bed, venting and purging of the bed, and cooling of the bed. Multiple beds can be cycled between CO.sub.2 capture and regeneration, during which captured CO.sub.2 is recovered. Off-gas from a CO.sub.2 capture bed can be used in regenerating a parallel bed for increased efficiency.
