Скачать или смотреть Ash Content Analysis of Solid Samples | Step-by-Step Furnace Method

In this video, we demonstrate the determination of ash content in solid samples such as biochar, soil, and other environmental materials using a muffle (thermal) furnace method, following standard ASTM procedures.
The experiment is carried out from scratch, starting with accurate weighing of the solid sample, followed by high-temperature ignition in a muffle furnace, and finally calculating the ash content (%) based on mass difference.
This procedure is commonly adopted in environmental engineering, soil science, and biochar research to quantify the inorganic (mineral) fraction remaining after complete combustion of organic matter.
🔬 ASTM Standard Methods Referenced
ASTM D1762-84 – Standard Test Method for Chemical Analysis of Wood Charcoal (commonly used for biochar ash content)
ASTM D1102 – Standard Test Method for Ash in Wood
ASTM D2974 – Standard Test Methods for Moisture, Ash, and Organic Matter of Peat and Organic Soils
📌 Note: Selection of the ASTM method depends on the type of solid sample (biochar, soil, peat, or biomass).
