An improved method of extraction, detection, and characterization of a vapor from an explosive, a taggant in an explosive, a controlled substance, a biohazard, and mixtures thereof uses a new and improved SPME device for extraction and ion mobility spectrometry for detection and characterization. The new and improved SPME device has an increased capacity to sorb a target vapor. The increased sorption of vapor provides for more accurate detection by an ion mobility spectrometer. A SPME device having increased surface area may be exposed to an atmosphere in an enclosure containing a test object or a volume of gas that was in contact with the test object to allow for sorption of the target vapor and then introduced into an IMS for more accurate detection and characterization of the vapor due to the increased sorption of the vapor by the SPME device described herein.

A biohazard safety enclosure or workstation particularly adapted for enclosing automated instrumentation includes a chamber defined by front, back, top, bottom, and opposed end walls; a HEPA filter across an air inlet opening into the chamber, and an airflow means to direct air horizontally through at least part of the chamber between the end walls. Preferably, the workstation has a second HEPA filter across an air outlet opening in the work chamber, with the airflow means including a conduit extending from the air outlet opening to the air inlet opening. A fan draws air through the conduit. A part of the filtered air is exhausted from the workstation and is replenished through a make-up air inlet into the chamber.

A mobile containerized autopsy facility for use in distant contamination zones, comprising at least one enclosure which includes at least one seamless and sealable compartment, which compartment meets biohazard safety level 3 and 4 requirements. The facility consists of enclosures that are most commonly a conversion of at least one standard 40×8×9.5 foot refrigerated cargo container that may be easily transported by trailers or by air to remote sites and be operational without the dependence on local infrastructure.

A microradio is provided with a hysteretic switch to permit an optimum range increasing charging cycle, with the charging cycle being long relative to the transmit cycle. Secondly, an ensemble of microradios permits an n2 power enhancement to increase range with coherent operation. Various multi-frequency techniques are used both for parasitic powering and to isolate powering and transmit cycles. Applications for microradios and specifically for ensembles of microradios include authentication, tracking, fluid flow sensing, identification, terrain surveillance including crop health sensing and detection of improvised explosive devices, biohazard and containment breach detection, and biomedical applications including the use of microradios attached to molecular tags to destroy tagged cells when the microradios are activated. Microradio deployment includes the use of paints or other coatings containing microradios, greases and aerosols. Moreover, specialized antennas, including microcoils, mini dipoles, and staircase coiled structures are disclosed, with the use of nano-devices further reducing the size of the microradios.

A biological safety cabinet includes a work chamber having a contaminated air discharge opening, a fan enclosure above the work chamber, a conduit extending from the chamber air outlet to the top of the fan enclosure, a first HEPA filter in the top of the fan enclosure, a second HEPA filter between the fan enclosure and the work chamber, and a fan within the fan enclosure to convey air through the conduit from and the first HEPA filter into the fan enclosure, and to discharge air under positive pressure from the fan enclosure through the exhaust port and through the second HEPA filter into the work chamber. Due to the construction of the cabinet, the fan can be repaired or replaced without the need to observe biohazard procedures.
