Abstract
Most fission track dating laboratories currently separate apatite (density ≈3.1–3.2 g/cm3) from zircon (≈4.5 g/cm3) in separatory funnels using the heavy liquid methylene iodide (MEI, density 3.32 g/cm3). We have found it better to undertake these separations using MEI in glass constriction tubes nested inside 15 ml glass test tubes. This procedure is considerably more efficient than the separatory funnel method provided sample sizes are smaller than about 250 mg.
