Title

Analysis Of Gases In Metals

Description

This investigation has been undertaken to determine the feasibility of using gas chromatographic techniques in the determination of nitrogen in metals. The resolution of extracted nitrogen, hydrogen, oxygen and carbon monoxide by a molecular sieve 5A chromatographic column is demonstrated. The chromatographic sensitivity is shown to be adequate for part per million determinations.

An apparatus which combines gas extraction from metallic samples, gas transfer, and chromatographic analysis is described and recommendations presented for further improvement in system operation.

The application of the basic principle for the determination of nitrogen in magnesium and ingot iron with the developed apparatus has been investigated. To date these determinations gave largely negative results; reasons for the failures are attributed to apparatus shortcomings and corrective measures are proposed.

Extension of the analytical method to inert-gas fusion extraction is discussed.
