Simultaneous Determination of Oxygen and Nitrogen in Steels by a D.C. Carbon-Arc, Gas Chromatographic Technique.

Simultaneous Determination of Oxygen and Nitrogen in Refractory Metals by the Direct Current Carbon-Arc, Gas Chromatographic Technique.

“…and which the authors feel is a possible basis for the development of instrumentation for monitoring phosgene in the atmosphere. The method utilizes the electron capture detector (3) which is sensitive to most halogenated compounds. Under the conditions used in the laboratory, a determination can be made every 6 minutes.…”

Ferrous Metallurgy

“…Of the steps in determining nitrogen in metals, the decomposition step is the source of most problems. Studies intended to improve this step were reported for both the chemical (12,96,115,140,165) and hot extraction (47,49,96,140,163,165,207) procedures.…”

Critical Evaluation of a Platinum-Bath, Vacuum-Fusion Procedure for the Determination of Oxygen and Nitrogen in Steels.

“…Assay the formaldehyde (37%) solution (7). Weigh accurately about 3 grams of this solution and dilute to exactly 1 liter.…”
