Non-destructive Filling Weight Determination of Solid Drug Powder in Crimped and Non-crimped Vials / Feasibility study using TD-NMR spectroscopy · Witt K, Posset T · Roche Diagnostics GmbH, Mannheim, Germany
Drug powder IPC method Non-destructive Solid TD-NMR Vials In recent years TD-NMR (time-domain nuclear magnetic resonance) spectroscopy has gained importance in many different fields. The major user of this new form of spectroscopy is the foodstuffs industry [ 1 ]]. In the pharmaceutical industry, however, this method is also gaining in importance. We have shown, for instance, that the filling weight of parenteral drugs in syringes and/or vials can be determined non-destructively [ 2 ]. This measuring principle is a so-called „at-line filling weight control”, in which the syringes/vials can be returned to the process. This is also the major ...
