Abstract
Measurements have been performed using several example powders and mixtures. Results show that the probe can separate signals from the drug and additive particles. Care has to be taken in interpreting the signals due to particles colliding with the grid and exchanging charge with it. Results were also verified by separating the aerosol physically using a high electric field separator. Separated particles were identified optically and also by using a differential scanning calorimeter. (C) 2003 Elsevier Science B.V. All rights reserved.
