Description
The Catalytic Instruments CVF100 catalytic vapor filter is plug-and-play portable device that is compatible with all brands of condensation particle counters (CPC’s). It may also be used with different brands of SMPS (scanning mobility particle sizing) systems incorporating condensation particle counters and other types of equipment as well. In laboratories and indoor environments butanol vapor from butanol based CPC’s and other equipment is generally released into the atmosphere as an environmental pollutant or it is released into the laboratory, where it is a potential health hazard.
Some organizations do vent this exhaust outside however others don’t or cant. Using a portable catalytic vapor filter in conjunction with a butanol based CPC, SMPS system or other equipment can remove 99.99% of the butanol vapor emitting clean CO2 and H20 gas only.

Indoor Measurements
In laboratories and indoor environments butanol vapor from butanol based CPC’s and other equipment is generally released into the atmosphere as an environmental pollutant or it is released into the laboratory, where it is a potential health hazard. Some organizations do vent this exhaust outside however others dont or cant. Using a portable catalytic vapor filter in conjunction with a butanol based CPC, SMPS system or other equipment can remove 99.99% of the butanol vapor emitting clean CO2 and H20 gas only.
Having your own portable Catalytic Instruments CVF100 catalytic vapor filter in your laboratory provides tremendous flexibility. This can be used with any butanol based CPC, SMPS system and or related equipment on the market. You wont be locked in to using one piece of equipment from any manufacturer. These devices may be used indoors or outdoors allowing customers to utilize existing or new butanol based devices for quality particle measurements. Many of the world’s leading metrology institutes, universities and aerosol research groups already use these devices and Catalytic Instruments technology is used inside or alongside many particle instruments provided by global particle equipment manufacturers.
Outdoor Measurements
Environmental agencies measure ultrafine particles especially in areas with heavy traffic. Ethene is commonly used as tracer for traffic and is monitored by the ambient air stations. The Catalytic Instruments CVF100 is used to measure the concentration of Ethene in the range of ppm is highly cross-sensitive to butanol. Hence no butanol vapor can be present when measuring Ethane. In order to remove 99.99% of the butanol vapor emitted by CPCs, a catalytic vapor filter is the method of choice. The catalytic vapor filter oxidizes the butanol vapor to CO₂ and H₂O and effectively removes the butanol, making accurate measurements of Ethene possible.
