Many diverse industries use ash analyses for quality control, but conventional muffle furnaces can take hours to ash a sample. Microwave technology can reduce ashing times to minutes, making ash analysis practical for both process and quality control. CEM’s innovative furnace design ashes up to 15 samples at a time and allows to use any type of crucible normally utilized in conventional muffle furnaces (metal, porcelain, graphite, glass, quartz fibre).
The Phoenix Microwave Ashing System is available with your choice of either a High Temperature or High Capacity furnace. The High Temperature furnaces reach 1,200 °C and can process up to eight 25-mL crucibles. For laboratories needing greater throughput, the High Capacity furnaces reach 1,000°C and hold up to fifteen 25-mL crucibles.
The Phoenix Airwave Microwave Muffle Furnace meets the most demanding requirements of large organic samples with ease. This microwave muffle furnace utilizes a patented air amplified exhaust system to quickly and safely ash samples, removing large quantities of air and volatile by-products.
The Phoenix Airwave Microwave Muffle Furnace is also available in 2 versions: High Temperature and High Capacity.
The CEM Phoenix Microwave System with Sulfated Ashing Option is a microwave muffle furnace that allows the pharmaceutical industry to perform Residue On Ignition (ROI) or Sulfated Ash tests for the evaluation of raw materials, excipients and quality control for finished products while safely removing and neutralizing Sulfur and Nitric Acid vapors.
The system eliminates procedures that are operator-dependent, such as Bunsen burners, heat lamps, and hot plates. Computer control of multi-stage methods allow each step to be quantified for documentation and validation and frees laboratory personnel for other tasks.
An NIST traceable Dual Thermocouple allows simultaneous measurement of the furnace chamber temperature by an appropriate digital temperature meter. The software in the Sulfated Ashing System, in conjunction with the NIST traceable Thermocouple Calibration Source Instrument, allows calibration of the temperature controller with the time and date recorded in the computer memory to be displayed or printed.
CEM’s unique, patented quartz fiber crucibles dramatically reduce ashing times and cool in seconds. The quartz fiber material allows oxygen to circulate around the sample speeding combustion even with our unique crucible caps in place.
