What is LECO used for?

Since 1936, millions of samples worldwide have been analyzed using LECO instruments for elemental analysis, thermal analysis, metallography, and mass spectrometry.

What is LECO analysis?

LECO analysis is a reliable method for determining the concentration of elements within a metallic sample, including Carbon, Hydrogen, Nitrogen, Oxygen and Sulfur. Our trusted experts help manufacturers better understand the properties of their material.

How does CHN elemental analysis work?

In CHNS elemental analysis, solid samples are combusted and the resulting oxides of carbon, hydrogen and sulphur along with nitrogen are analysed sequentially.

How does an elemental analyzer work?

Elemental analyzers work by heating an element quickly to a sufficiently high temperature so that it combusts. It is then passed through the analyzer in its gaseous state. A detector detects the elements present, and the researcher reads this information on a computer screen.

How do you test for nitrogen in steel?

A rapid semimicro method for the determination of nitrogen in steel is described. A 0.5- to 1.0-gram sample is usually required, and the nitrogen is put into solution as ammo- nium sulfate by suitable treatment of the sample with sulfuric acid.

What does an elemental analyzer do?

How accurate is elemental analysis?

Analysis of results The accepted deviation of elemental analysis results from the calculated is 0.3%.

What instrument is used for elemental analysis?

For elemental analysis, this is either mass spectrometry (MS) or optical emission spectroscopy (OES).

What is N in steel?

Nitrogen as an alloying element in steel is being used since 1940s initially to produce stainless steels as a substitution for nickel. The use of nitrogen in high alloy steels has a number of advantages. These advantages make nitrogen as an interesting alloying element.
