LECO analysis is a method for reliably determining the concentration of gases within metals and oxides, including Carbon, Hydrogen, Nitrogen, Oxygen and Sulfur. We do this by using infrared absorption and thermal conductivity to measure combustion gases within a metallic sample.
Especially in metals, small amounts of these light elements can cause havoc because they form hard particles that act like ceramics that dramatically affect the product’s properties.
Because ICP and LECO each specialize in detecting different element types, running your product through both allows you to see the whole picture and have greater confidence in your product.
