The Bobcat is a light-weight, portable, dry filter air sampler with a unique rapid filter elution kit. It is ideally suited for the collection of bio-aerosols and particulate matter; including sub-micron sized particles, airborne molecular contamination, and particulates. This system has been developed to address a broad range of air sampling requirements.
Perfectly suited for use with rapid molecular analysis methods.

Attributes of the Bobcat

• 200 LPM
• Lightweight, only 7.8 lbs with battery
• Built-in tripod
• Omni-directional aerosol inlet
• Easy to read status display
• Built-in mass flow sensor for consistent sampling rates
• 4 programmable run modes allow the user to balance collection rate with battery life
• Disposable, single use filter and elutor components– no need for decontamination
• No liquids in the collector allow for use in extreme temperatures
• Eluting captured particles from the filter takes only 5 seconds; sample is ready for analysis in less than one minute
• Easy to use–operators can be trained in 10 minutes
• Controls can be manipulated with gloved hands, while in full NBC gear
• Designed for use in high-stress environments
• Single electrical port allows for remote triggering, data acquisition, and external power supply with one connection

The system uses a dry 52 mm electret filter as the collection media. Electret filters are made with a combination of positively and negatively charged fibers. This substantially increases the collection efficiency of the filter and allows for the use of lower pressure drop filters which, in turn, allows for higher sampling rates for extended periods using battery power. Additional advantages include low consumable costs, ease of use, and high durability. This gives it the ability to operate at low temperatures; a limitation for most wet-wall cyclone type collectors.

Rapid filter sample recovery

Following aerosol collection, the Filter is removed from the Collector, snapped onto the Sample Cup and fitted with the Elutor Cap. To extract the captured particles from the filter, the user presses a Canister containing the elution foam into a fitting on the Elutor Cap. The elution foam is released from the Elution Canister evenly through the Filter. The wet foam passes through the interstitial spaces of the filter to efficiently extract any captured particles. Sample elution takes approximately 5 seconds and produces 6 to 7 milliliters of liquid sample. The foam immediately collapses back to a liquid in the sample cup, making it available for sample processing and analysis
