Does anyone know a good supplier for a radio-frequency plasma asher for low
temperature removal of organics from carbonates/phosphates (bone)prior to
isotopic analysis, I have had some difficulty in sourcing one of these
instruments since our old one died. In addition if anyone has or knows of a
phosphate material of known d18O composition I would be interested in
hearing from them as I am involved in measuring the oxygen isotope
composition of biogenic phosphates. Thankyou very much.
