XMX/CV Aerosol Sample Collector - Civilian Version

The XMX-CV Aerosol Collection System is a civilian version of Dycor’s successful XMX/2L-MIL collector, designed and built in response to the need for a weatherproof, outdoor aerosol collector.  The XMX-CV has been sold to various first-responder and public health organizations around the world.

The XMX-CV is an aerosol separator, sample preparation, and high mass flow concentrator system, designed to operate under harsh field conditions.  This system was designed to process and collect large concentrations of aerosols in the respirable range (1 to 10 microns in diameter) in relatively short periods of time, i.e., when the cloud is over the XMX.  This system collects high volumes of air, strips away the large dust particles and the very small micro debris and concentrates the aerosols of interest.  The particles are then impinged into a sample collection vial (centrifuge tube) containing customer specified liquid (normally type 1, sterile water or phosphate buffered saline). Once the sample is collected, the user removes the centrifuge tube for subsequent analysis (immuno-assay, PCR, culturing). One of the primary issues in bioaerosol detection is the fact that it is difficult to obtain enough sample of interest to detect an airborne threat concentration that is lethal to humans.  Our system captures high concentrations of particles and prepares a small aqueous aliquot for analysis with minimal dilution.

Additionally, our XMX system is designed to operate under field conditions, while wearing full Personal Protective Equipment (PPE). There is superior system reliability, with only two moving parts, to reduce maintenance and ensure a high MTBF.  The XMX system is quick and easy to set up and tear down to minimize training and improper or incorrect usage.  The internal separator and collector components are easily disassembled to facilitate decontamination with various decontamination solutions, while maintaining part durability.  This feature minimizes operator effort to reduce the possibility of cross-contamination between collection missions.  This system comes with a high-strength transport container for increased mobility and portability (one person).

For dry collection applications, an alternative option is a dry filter that replaces the liquid vial. The particles, rather than impinging into water, are impacted onto the dry filter which is then removed and dissolved in liquid for further analysis. The filter adapter is an option, and the filter cartridges are COTS and are readily available. Depending on the application, a dry filter may be advantageous.
