Ashing at 60-80⁰C in an Ozone atmosphere followed by disruption by ultrasound has been successfully used to prepare plant samples for slurry ETA-AAS . Although the sample preparation time is as long as 5 days the system needs no operator input and for plant microanalysis the system offers significant opportunities. The low temperature ashing prevents loss of volatile analytes. The system currently in use is a set of laboratory built glass chambers each capable of holding 3 samples. The heating has been carried out in a, modified, redundant GC oven.
