Compact analyzer for online monitoring of blending processes BlendAlyser - latest development for contact-free online monitoring of powder blending processes. This instrument is well tailored for the needs of pharmaceutical industries and research establishments.
2. Definition: Blending process Definition: Blending (process engineering): Main aim of the blending process is the production of a blend whose sample reflects exactly, or at least by pre-defined accuracy, the ratio of the added base materials. Pharmaceutical industry – solid blend of agent (API) and several additives (up to 10)
Main goal of blending processes in pharmaceutical industries: Tablet production which requires identical ingredients and homogenous distribution of the active pharmaceutical ingredient (API) as well as additives.
Principle of tablet production Active substance synthesis Blending and Granulation Compression Coating Package
Schematic blender design Active Pharmaceutical Ingredient (API) Excipients Measurement window to which the BlendAlyser is mounted
Problems which may arise during blending processes • inhomogeneity in material blends • deblending due to exceeded blending times • increased time and cost consumption due to exceeded blending times • general failures Solutions: Sampling at the blender offline lab analysis of material mixture (e.g. by HPLC) Online process monitoring enabling the moving blender is no longer necessary, online blend analysis, immediate results
3. Process monitoring with the BlendAlyser • Features • solid end point detection of blending processes • avoids deblending • online analysis of blending and production processes • quantitative analysis of different ingredients
BlendAlyser Connection via 4“ standard flange using a flange fastener Blender system The measuring instrument is directly mounted to the blender. Measurement is performed online.
Advantages: • optimized production processes • improved process knowledge • expensive and time consuming laboratory analysis are no longer • necessary • improved quality assurance • time and cost savings • real-time analysis

Different ways for determining homogeneity • monitoring of standard deviations within a certain spectral • range (e.g. Moving Block StdDev I) • absorbance monitoring at significant peaks • quantitative analysis (e.g. concentration determination • using PLSR) • PCA (Principal Component Analysis)
Homogeneous blend Previous blending time End point detection via Moving Block Standard Deviation I of absorbance at selected wavelength ranges
End point detection by absorbance determination at signification peaks Homogeneous blend Addition of magnesium stearate in order to improve miscibility
End point detection by measuring API’s concentration variations – determination of chemometric calibration Homogeneous blend
End point detection via PCA (Principal Component Analysis) Homogeneous blend till addition of magnesium stearate after addition of magnesium stearate
