LECO Nitrogen / Oxygen Determination
Nitrogen is sometimes required for testing. Stainless steels typically require nitrogen testing if the material has a maximum or minimum nitrogen requirement in the alloy requirements. CMS performs this testing on a specific LECO Combustion Nitrogen/Oxygen unit. CMS uses a LECO TC-436 Nitrogen-Oxygen determinator to perform analysis on metal samples. The range of this machine can accurately measure nitrogen from 0 ppm to 5000 ppm or .00%-.50% ranges. The accuracy of this machine is ±2 ppm or ±3% whichever is greater. Samples can be introduced in solid, milling or powder form. It can determine nitrogen content in iron, steel, slag, and other ferrous or non-ferrous materials. This testing is the most accurate way of testing nitrogen content in materials. Feel Free to contact us with questions you may have regarding getting Nitrogen testing on your material.
Oxygen is sometimes required for testing. Coppers and titanium are two metals which typically require oxygen testing. CMS uses a LECO TC-436 Nitrogen-Oxygen determinator to perform analysis on metal samples. The range of this machine can accurately measure Oxygen from 0 ppm to 1000 ppm or .00%-.10% ranges. The accuracy of this machine is ±2 ppm or ±2% whichever is greater. Samples can be introduced in solid, milling, or powder form. It can determine oxygen content in iron, steel, and other ferrous or non-ferrous materials. This testing is the most accurate way of testing Oxygen content in materials.
