source site The PYRO with High-Throughput Setup accommodates up to 24 Milestone quartz fiber crucibles. A unique,
rugged, solid, microwave–transparent, ceramic muffle allows microwave radiation to pass through and rapidly
raise the temperature of a silicon carbide plate. Sample crucibles are placed on a large clean quartz plate and
an airflow is induced by a built-in exhaust system.
A porous ceramic honeycomb frit built into the wall of the muffle furnace allows a constant stream of air to pass over the sample crucibles. The combination of microwave “superheating” and induced airflow results in a dramatic reduction of the ashing time.
click here As the name implies, the PYRO with Ultrafast Setup has an extremely fast heating rate. A typical ashing temperature of 800°C can be reached in just 5 minutes, starting from room temperature!
This eliminates the need of running the system overnight, and avoids the lengthy heat up time associated with electrical resistance furnaces, dramatically lowering the power consumption and cost.
kennenlernen webseiten Ashing of pharmaceutical, polymers, and food samples often involves the use of sulfuric acid. Hot sulfuric acid vapors are hazardous to analysts and corrosive to equipment. Additionally, sulfate ashing methods are laborintensive and time-consuming, requiring manual fuming of the acid and 8-12 hours to be completed. To overcome these issues, Milestone has developed the Sulfated Ashing Setup.
