WitrynaUSP defines the Permitted Daily Exposure (PDE) limits for the regulated inorganic (elemental) impurities: As, Cd, Hg, Pb, V, Cr, Ni, Mo, Mn, Cu, Pt, Pd, Ru, Rh, Os and Ir. USP defines the sample preparation options and validation protocols that must be followed to demonstrate accuracy, repeatability, and the “unequivocal” identification of … Witrynac in the newly discovered Cr-based superconductor K 2Cr 3As 3. The resistivity measurements show that the crystals prepared using high-purity Cr metal (99.99%) have an electron mean free path much larger than the superconducting coherence length. For the crystals prepared using impure Cr that contains various non-magnetic …
