ATS generally uses a LECO Combustion instrument to analyze carbon and sulfur content is steel samples, especially when they are geometrically small.
Small pieces of metal samples that cannot be “sparked” on a spectrograph due to size constraints can be analyzed by LECO combustion.
Combustion testing is a technique used to precisely determine the content of carbon, sulfur, nitrogen, oxygen, and hydrogen in metals and alloys. Fundamentally, this process involves burning of the sample to release these specific elements. Values received for element percentages are matched against specifications to determine the metal type. ATS predominately performs this analysis on steel samples in addition to iron, nickel, titanium, and cobalt alloys. Our chemists regularly perform this testing in accordance with ASTM E1019, E1447, and E1941.
Analytes Commonly Tested Using LECO Combustion Include:
Steels and Cast Irons
Reactive Materials
Refractories
Non Ferrous Alloys
Carbides
Carbon
Sulfur
Nitrogen
Oxygen
Hydrogen
