How it works

Ashing test procedures performed on pharmaceutical, polymer, and food samples frequently involve the use of H2SO4. Hot sulfuric acid vapor released during these procedures is both hazardous to analysts and corrosive to equipment. In addition to these complications, sulphate ashing procedures are typically labor-intensive and timeconsuming, requiring manual fuming of acid from crucibles and 8-12 hours to complete. Milestone has engineered a unique microwave system for sulphate ashing procedures.

The PYRO Sulphate Ashing system enables analysts to add H2SO4 to samples and place crucibles directly into the microwave muffle furnace without a preliminary charring step. Tedious handling/monitoring of samples, and operator exposure to acid fumes, are eliminated.
In fact, sulfuric acid fumes released from crucibles inside the muffle furnace are continuously removed, through a quartz tube connected to an air-cooled quartz collection vessel mounted outside of the unit, and to the VAC-1000 acid scrubber module.

The labstation is designed for complete operator safety and long life, and performs the complete procedure in only 60-90 minutes.
