Instrumental Gas Analysis | |
Instrumental Gas Analysis (IGA) refers to a set of analytical techniques for accurately measuring Carbon (C), Sulfur (S), Oxygen (O), Nitrogen (N), and Hydrogen (H) content in a range of solids including metals and alloys, ceramics, metal oxides, metal sulfides, slag, and cement. The samples can be in the form of small blocks, chips, powders, pins, or granules. IGA methods, also termed Elemental Analyzers, convert these elements to gaseous form and detect them by infra-red absorption or thermal conductivity detectors. The techniques used in IGA include combustion analysis for C and S, and Inert Gas Fusion analysis for O, N, and H. Combustion analysis for C and S determination, using IGA, involves combustion of the solid sample and infrared detection of the combusted products. The solid sample is placed in a ceramic crucible or boat within a furnace, in the presence of an Oxygen gas stream. The high-temperature furnace (~1500 0C) can be a resistance type with precise temperature control or an induction furnace with precise current control to achieve optimum results. Due to the Oxygen-rich environment in the furnace, C and S in the sample are oxidized to form carbon dioxide (CO2) and sulfur dioxide (SO2), respectively. A small amount of carbon monoxide (CO) can also be produced, depending on the concentration of C in the sample. The extracted gases from the furnace are passed through a gas purification system, to a Non-Dispersive Infrared Detector (NDIR) system for quantification. INFINITA LAB  | |
