Our helium is good for nothing. If you bought our helium to do nothing and it did something, you'd probably do something to us. So we do something to make sure our helium does nothing. We keep împuntîes out. In fact, we know how to keep all but .0001% of them out (For critical applications, our Rare and Specialty gases
department sells helium that is 99,9999% pure. The purest you can buy.) If you'd like to know more about a gas that does less, call Hank Grieco (201) 464-8100. Or write to him at Airco industrial Gases, 575 Mountain Avenue, A Murray Hill, New / ί Ι Η Π Π Jersey 07974. f f \ Λ, Industrial Bases
