Air Sampler for PFAS FM4/GAIAC

Air Sampler for PFAS FM4/GAIAC

Air Sampler for PFAS(FM4) is new Low Volume Air Sampler which you can analyze PFAS in the particle and gas in one sampling.
The FM4 has a multi-stage design in which each stage is configured to collect a particular type of target substance and incorporates a collection material optimized for that target type. For instance, as well as using our newly developed GAIAC activated carbon disks, two of which are mounted in the unit’s sampling holder, the FM4 employs quartz-fiber filters and a polyurethane foam (PUF) adsorber.
This multi-stage design allows the FM4 to simultaneously analyze ambient air for both particulate PFAS and gaseous PFAS. This means you can carry out a comprehensive analysis with just a single sampling operation.


・Comprehensive Sampling
Despite its compact size, the FM4 Air Sampler can simultaneously collect both particulate and gaseous substances. It allows the amount of each substance collected to be separately determined, making it possible to comprehensively evaluate the sampled air.

・Capable of Collecting Gaseous PFAS such as FTOHs
Up to now, it has been difficult to collect gaseous PFAS in the air. However, thanks to the FM4 Air Sampler’s newly developed activated-carbon desorption material, this is no longer a problem.

・Excellent Recovery Rate
We have tested the FM4 Air Sampler with a wide range of PFAS and have achieved excellent recovery rates for all of them.

・Portable and Easy to Deploy
Because the FM4 Air Sampler is lightweight and compact, it is easy to carry and, with its very small installation footprint, easy to deploy.
