2.3 Methods C and D — Ash content of a peat or organic soil sample is determined by igniting the oven-dried sample from the moisture content determination in a muffle furnace at 440°C (Method C) or 750°C (Method D). The substance remaining after ignition is the ash. The ash content is ex­ pressed as a percentage of the mass of th Selecting an ash test method T 211 vs T 413 vs T 244 can be confusing. It is often used to give an estimate of the silica content of pulp or paper even though other minerals can be present. Sand and acid insoluble Ash are similar but the sand determination utilizes screening so only particles >0.074 mm are quantified 3. Determination of ash content (AOAC, 2000) Method 1. Place the crucible and lid in the furnace at 550 °C overnight to ensure that impurities on the surface of crucible are burned off. 2. Cool the crucible in the desiccator (30 min). 3.

Scope. This International Standard specifies a method for the determination of the ash content of petroleum products, such as distillate and residual fuel oils, crude petroleum, lubricating oils, waxes and other petroleum products, in which any ash-forming constituents present are normally considered to be undesirable impurities or contaminants Methods for ash determination in meat and meat products are generally based on the drying and charring of the sample followed by its combustion until white or light grey ashes are obtained. There are differences, though, amongst the various recommended methods, as to charring procedure, ashing temperature and whether or not to add reagents in order to hasten the combustion As the ash quantity has to be related to dry matter, the moisture content of the test substance has to be determined separately. Definition Ash is defined as the quantity of mineral matter which, after application of the described working methods, remains as incombustible residue of the tested substance AOAC Official Method 942.05, Ash in Animal Feed, has been applied in feed laboratories since its publication in the Official Methods of Analysis in 1942.
