CEM
The fastest muffle the world
Under ashing in a muffle furnace means the thermal decomposition of hydrocarbon products, leaving the inorganic constituents back. So conventional muffle furnaces are used for a long time for a variety of incineration. In a sample is weighed into a crucible, which was previously dried and tared or annealed. Subsequently, the sample material is placed in a convectively heated muffle, where it remains in the normally several hours to constant weight. Then the pot is removed from the oven and given to cool for about an hour in a desiccator, place before one can Rückwiegung. This relatively simple process is extremely labor-and time-consuming, which is mainly in the production and quality control is a major problem and prevent a quick access to ongoing productions. This often caused inferior goods outside the specifications given by the reduced and reducing product quality were also the proceeds of the manufacturer. In addition to the current production is a rapid determination of ash content also receiving inspection of raw materials and in research and development of great importance.
The remedy here is to microwave Muffelofensysteme of CEM: The Phoenix, the Phoenix and the Phoenix Airwave SAS. The applications of these systems are:
- Dry ashing of food, animal feed, grain goods, etc.
- Determination of loss on ignition and the ignition residues
- Structure determination of filling substances
- Furnaces, for example, for elemental
- Drying, annealing and heat treatment
- Determination of sulphate ash gem. Pharm Eu. and DAB
The advantages of this technique are a drastic time reduction and a "clean" work. The built-in exhaust system removes smoke and steam independently. As required by the conventional technique used to hours, with microwave technologies now in minutes erreicht.Die tedious, dirty and time-temperature applications up.

Results of the comparison Vera Chung
The following table shows the drastically reduced ashing times for a variety of materials. Besides the materials listed in the table, all other methods Built Muffle be processed in conventional, such as aluminum oxide, carbon black, citric acid, mineral oil products, chewing gum, milk powder, resins, polycarbonate, polyetherimide, polyethylene (TiO 2filled and unfilled) , sugar, talc, etc.
The time saved from these listed substances is similar to the examples listed in the table.
