Pall introduces Gaskleen gas purifiers for HB-LED manufacturers

Pall Corp of Port Washington, NY, USA has introduced its Gaskleen High-Bright purifiers to remove molecular contaminants from ammonia used in the manufacture of high-brightness light-emitting diodes (HB-LEDs). According to the firm, the purifiers have a service life that is twice that of other commercially available technologies.

“With this new purifier, Pall has addressed the industry demand for the brightest LEDs at the lowest operating cost,” says Jan-Paul van Maaren, VP of strategic marketing, Pall Microelectronics. “The cost of LEDs needs to drop and the performance has to rise to accelerate the adoption of LED lamps as replacements for incandescent and CFL bulbs. This new technology will give our customers both a performance and cost advantage.” 

Gaskleen purifier assemblies combine Pall’s proprietary purification materials and Ultramet-L stainless-steel filter media. The purifiers remove moisture and other oxygenated compounds from process gases to sub ppb levels while providing 3nm or 0.4µm filtration. Furthermore, they do not release aluminum or other metal ions into the process stream, says the firm.
