Poster presentation at ISL-FD 9th International Conference 2-6th September, 2019, Ghent, Belgium Two IgG formulations, one with 5% sucrose and the other with 5% Mannitol:Sucrose (ratio 4:1) both in 20mM Histidiine 0.01% Tween 20 pH 6.5, were freeze dried in a Telstar freeze dryer equipped with Pirani and Baratron sensors and a Sciospec® five-channel through vial impedance spectroscopy (TVIS) system. The TVIS parameter C'(100kHz) (i.e. the real part electrical capacitanc... Mehr ...
