Determining the amount of carbon and sulfur in iron, steel, nickel, and cobalt alloys represents two major quality metrics for these materials. The CS844 utilizes a high-efficiency induction furnace to quickly break down these materials and allows rapid determination of carbon and sulfur. LECO Ref. #230-821-423

Two-dimensional gas chromatography (GCxGC) analysis of individual chemical components of a Citronella essential oil sample with LECO Pegasus® BT 4D. LECO Ref. #203-821-611

Determining and identifying individual analytes within a complex sample can provide important information to better understand a product or process. This exploratory analysis is readily accomplished with GC-TOFMS, as it provides non-targeted data with every acquisition. The Pegasus BT adds to the chromatographic separation by taking advantage of the full mass range data with mathematical deconvolution to further separate chromatographic coelutions. These capabilities provide excellent information about a sample and the ChromaTOF brand software contains tools to help streamline data analysis.

Gas Chromatography Mass Spectrometers are excellent tools for the analysis of essential oils (plant extracts) - the analytes of these extracts are readily separated, identified, and quantified. In this app note, Mint is analyzed. LECO Ref. #203-821-609

The gross calorific value of biomass materials is most often used when calculating the total calorific value for a biomass quantity for fuel purposes. Gross calorific values are used to calculate thermal efficiency, mass, and/or volumetric heat of combustion. The LECO AC600 Isoperibol Calorimeter can be utilized to find this value.

Decarburization can be defined as the loss of carbon from the surface of iron-based alloys as the result of heating in a medium that reacts with the carbon. The surface of decarburized steel is softer than the core, and at times it is necessary to quantify the degree of decarburization. LECO Ref. #230-821-313
