JM-GPT supplies second hydrogen purifier to Taiwan’s Epileds

Johnson Matthey Gas Purification Technology (GPT) group of West Chester, PA, USA, which designs and manufactures bulk and point-of-use gas purifiers, has supplied a PSH-40 hydrogen purifier (capable of flowing 40Nm3/hr) to Epileds Technologies Inc of Tainan Science-Based Industrial Park, Taiwan for the manufacture high-brightness blue LED chips.

This is the second bulk hydrogen purifier that Epileds has bought from Johnson Matthey (following a GPT-20 hydrogen purifier, capable of flowing 15Nm3/hr, in late 2006).

Epileds is a joint venture formed in May 2006 between dynamic random access memory (DRAM) chip maker ProMOS Technologies and process equipment maker Hermes-Epitek, both of Taiwan, to manufacture blue LED chips.

Johnson Matthey says that its purifiers can provide 99.9999999%-pure hydrogen.
