1. Use of near-infrared spectroscopy to quantify drug content on a continuous blending process: Influence of mass flow and rotation speed variations

   out of 5 stars 

   Contributor(s):: Martínez, Lizbeth, Peinado, Antonio, Liesum, Lorenz, Betz, Gabriele

   The aim of this study was to develop a quantitative Near-Infrared (NIR) method which monitors the homogeneity of a pharmaceutical formulation coming out of a continuous blender. For this purpose, a NIR diode array spectrometer with fast data acquisition was selected. Additionally, the dynamic...

2. Solid Dosage Form Analysis by near Infrared Spectroscopy: Comparison of Reflectance and Transmittance Measurements Including the Determination of Effective Sample Mass

   out of 5 stars 

   Contributor(s):: Iyer, M., Morris, H. R., Drennen, J. K.

   Investigations into the near infrared analysis of intact tablets allow comparison of the reflectance and transmittance methodologies. The studies involved estimation of the effective sample mass and the effect of sample inhomogeneities. An empirical method for determining effective sample mass...

3. Effects of rotation rate, mixing angle, and cohesion in two continuous powder mixers-A statistical approach

   Contributor(s):: Portillo, PM, Ierapetritou, MG, Muzzio, FJ

   In this paper we examine the effect of rotation rate, mixing angle, and cohesion on the powder residence time and the content uniformity of the blend exiting from two continuous powder mixers. In addition, differences in mixing performance between the two blenders are examined. Analysis of...
