title: Phosphorus standards for the electron probe X-ray microanalysis of ultrathin tissue sections.
abstract: Phosphorus-containing standards for use during quantitative electron probe X-rays microanalysis of ultrathin tissue sections can be quickly and simply prepared using organo-phosphorus compounds which are soluble in Spurr's epoxy resin mixture. Trials of five such compounds (one solid, the rest liquid) are described.
