Our LECO TGA enables the simultaneous determination of Loss-On-Ignition (LOI) on multiple samples. By using a controlled atmospheric composition within the oven we are able to distinguish several characteristic parameters of the individual samples.
Generally, the precise determination of the changing weight of 19 samples positioned in a rotating carrousel while heating over a temperature range from ~25 to 1000 °C allows the analyses of their moisture, organic matter and (calcium-)carbonate content. Both versatile and rapid (~5 hrs/run) this technique serves as a robust basic analytical tool for diverse material composition. Typical sample amount necessary for a reliable analysis is 2 gram of homogenized material. Over 10 years of experience using the TGA on a very wide variety of sediments allows us to provide you with insightful information in addition to the precise analytical results.
