产品详细介绍
IAEA-B-4Tourmaline Mineral 11B
IAEA-B-4 was obtained from a composite sample of euhedral crystals of black tourmaline, near San Piero in Campo, Elba Island, and was prepared by the Istituto di Geoscienze e Georisorse, Pisa, Italy. Prior distribution into polyethylene bottles, the material was ground to a grain size ranging between 5 µm to 40 µm with a few larger grains of 100 µm, mixed and homogenized [1]. The recommended values of the quality control material are the results of the statistical evaluation of an interlaboratory comparison [2].
