Perma Pure and Baldwin Environmental: Baldwin Environmental was a leading manufacturer and service provider of stack gas emission monitoring equipment. Their product lines include heated filter probes, electronic water condensers, sample conditioning systems, and flow control drawers. They are now part of Perma Pure LLC but you will still find their name on products.

• Industrial Applications: Gas sample conditioning for process monitoring or environmental compliance monitoring. Stack gases must be conditioned to convert hot, wet and dirty gases into the cool, dry and clean samples required by analyzers. Perma Pure offers complete systems to accomplish this sample preparation as well as individual components for incorporation into other conditioning systems.
• Scientific Applications: Exploitation of the electrochemical and ion exchange properties of Nafion, as well as sample conditioning for laboratory analysis. Nafion is closely related to Teflon but has been chemically modified to make it function as an ion exchange membrane while still retaining the physical and corrosion resistance properties of Teflon.
