Perma Pure’s newly re-designed Web site, www.permapure.com, delivers gas conditioning information by product application for customers in the Scientific/Research, Medical, Environmental, and Fuel Cell fields. Better content organization and practical online tools aid in finding the best product fit. A number of Perma Pure’s products use a proprietary Nafion permeable membrane technology to remove moisture from gas sample streams, without altering the concentrations of typical analyte gases to be measured. Nafion’s unique properties also make it suitable for humidification of gas streams. Users can access product and technical information on the company’s range of gas conditioning products. A reference menu provides specific Nafion analyte retention information for a range of chemicals. A link to the NIST Standard Reference Data enables more detailed chemical research by formula and name. Embedded tools convert temperature and calculate dew point, with a link to download the company”s HumiCalc humidity conversion software.
