✦ Synopsis

Two dozen inorganic crystals, resins and other substances were surveyed in an effort to find a rapid method for separation of a broad spectrum of steroid hormones, including representatives of the androgen, estrogen, progestagen, and glucocorticoid classes. Magnesium oxide (MgO) was found to yield the best recoveries and separations with a great saving in time and effort, since MgO microcolumns could be rapidly poured, in contrast with those of Celite, which require repeated pouring followed by packing, and those of Sephadex LH-20, which are generally large and slow running.
