Water content of dried INFARM2 top simulant. Letter report, Revision 1

摘要

Pacific Northwest Laboratory received six simulated ferrocyanide sludge samples, INFARM2 top (INFARM2-REV-17), from the Plutonium Process Support Laboratory (PPSL) in mid 1993 for analysis of water content by Thermogravimetric Analysis (TGA) coupled to Fourier Transform Infrared (FTIR) for identification of the thermally evolved gases. The samples were dried by the PPSL prior to delivery according to three methods listed below. Two samples were provided for each drying method, samples 1-6. One additional sample prepared using drying method 3 was received in May of 1994 to check for possible reabsorption of water during storage, sample 7. The light green samples, sealed in clear glass screw cap vials, appeared uniform in color.
