Express Microwave Ashing System

QAsh achieves fast ashing times by combining in-situ air flow with a microwave. It has a large floor area to accommodate a large quantity of samples and is suitable for polymers, oils, food, pulp, sludge, and many other sample types.

Microwaves coupled with SiC are known to produce high temperatures at a much faster rate compared to old electrical heating furnaces. QAsh has a software controlled air inlet inside the ashing chamber which fuels the ashing process. The introduction of air at the source pushes ashing by-products out. An alumina fiber ashing chamber helps retain heat. This provides an efficient ashing process. Vertically placed SiC plates, in conjunction with ceramic insulation, create uniform temperatures across the ashing chamber. The R type thermocouple is encapsulated in a chemical resistant material. It measures temperatures accurately over the working range of 25°C to 1,200°C.
