Analysis of Ash Content in Polymers with Muffle Furnace


Ash is an inorganic remainder that left after heating the polymer at high temperatures in the presence of various oxidizing agents to remove the presence of water and organic matter. The determination of ash content in a particular product helps to measure the total amount of minerals within a product. Some analytical techniques are opted by following some measurable manner to provide complete information regarding the presence of content in the material. The most common methods that are used for ash determination are dry ashing and wet ashing. The test method is chosen for a particular analysis depending upon the reason to carry out the analysis. The inorganic residues that are left from heating can be in the form of anti-block, reinforcements, fillers, colorants, catalyst residues, etc.

The process of ashing is used to quantify the residual solids in the polymer and cannot be used to recognize the chemical components of the ash. The test procedure is commenced with the help of high-quality of a muffle furnace. Muffle furnace for ash content determination is limited to the materials that are stable till 900 degree Celsius such as polymers, rubbers.

Presto Stantest offers high-quality of Muffle Furnace with customized and user-friendly features. The device is designed as per the standards are given by ASTM, ISO, etc. The instrument offers highly accurate results.
