Ashing Furnaces

You can use furnaces for annealing, heardening, brazing, forging and nitriding. It has wide applications range through advanced materials, laboratory, dental, thermal process technology and foundry to glass and arts & craft.

WHAT IS ASHING?

Ashing in analytical chemistry is defined as the heating of a substance to leave only non-combustible ash, which is analyzed for its elemental composition.

ASHING TECHNIQUES

Dry Ashing

Dry ashing temperature 450°C to 550°C is usually performed by placing the sample in an open inert vessel and destroying the combustible (organic) portion of the sample by thermal decomposition using a muffle furnace. 

Sulfated Ashing

Sulfated ashing involves treatment of sample after charring using an open flame with sulfuric acid and then placing in a muffle furnace.

Low-Temp Ashing

Low-temperature ashing involves treatment of the sample at ~120°C using activated oxygen.
