Question/Answer

How are these used

For specific use instructions consult the sampling method of choice. Generally speaking a pump is attached to one side of the cartridge and a specific volume of air (generally measured by time of exposure and the capacity of the pump) is drawn across the filter. The cartridge is then capped and send to a lab for analysis.

can this be used to collect airborne silica in response to OSHA\'s new Silica Exposure standard?

The OSHA method for silica sampling says to use preweighed, 37 mm, 5 um, 3-piece, PVC cassette with a cyclone sampler. The cassette that you would need is CU37500PVCPW. We do not sell cyclone samplers.

I would like to know who makes the cassetts and filters, thanks in advance, Dra. Murillo
