The determination of ash content is an important test procedure, performed in thousands of laboratory each day, for process and quality control purposes. The new Milestone Ethos M is an advanced microwave ashing muffle furnace, suitable for many applications including ashing, sulphated ashing, large scale ashing, loss on ignition (LOI), residue on ignition (ROI), and fusion. The system is available in 3 interchangeable configurations – high sample throughput, ultrafast heating, and sulphated ashing making it a highly efficient alternative to conventional muffle furnaces.
