This method is used for the determination of moisture content, ash content and percent organic matter in peats, and other organic soils such as organic clays, silts and mucks. The moisture is determined by drying the sample at 105 °C. Alternately, the moisture can be evaporated at room temperature and then oven dried at 105 °C. The ash content is determined by igniting the oven dried sample obtained from the moisture content determination in a muffle furnace at 440 °C and 750 °C.

* The analytes and detection limits listed for each method represent the typical detection limits and analytes reported for that particular method. Keep in mind that analyte lists may vary from laboratory to laboratory. Detection limits may also vary from lab to lab and are dependent upon the sample size, matrix, and any interferences that may be present in the sample.
