WitrynaAbstract. In this paper, impurity parameters m i and k i have been calculated for a range of impurities I as detected in the eutectics Co-C and Pt-C, by means of the software package Thermo-Calc within the ternary phase spaces Co-C- I and Pt-C- I. The choice of the impurities is based upon a selection out of the results of impurity analyses … Witryna1 PART I: IMPURITIES: GUIDELINE FOR RESIDUAL SOLVENTS Having reached Step 4 of the ICH Process at the ICH Steering Committee meeting on 17 July 1997, this Guideline is recommended for adoption to the three regulatory parties to ICH 1.
