Combination with Image Analysis:

Combining spectroscopic data with morphological information, such as particle size and shape, provides access to an array of characteristics that were previously unavailable. For example, the new methods allow for the specific chemical characterization of hundreds of elongated, fibrous or more compacted round particles. These technological advances bring a whole new dimension to particle analyticsl. The ability to determine relevant particle characteristics and the capacity to set tailor-made parameters for specialty products such as dry powder inhalers design sets this technology far apart from it's competitors.

Automated Spectroscopy - Statistical Relevance:

Automated analysis systems provide objective results. It is impossible for an operator to select hundreds or thousands of particles as small as 2-500μm for spectroscopic analysis individually. Ultimately, the result will be subjective because the user tends to develop a liking for particles which yield beautiful spectra or have a distinctive shape. The Particle Explorer lets you obtain reliable unbiased results.
The automated Raman spectroscopy system selects the appropriate laser intensity and exposure time to achieve optimal spectra. Intended for smaller particles and a rapid completion, the standard version provides a reliable particle spectrum within 10 to 60 seconds.The newly-developed Ultra Raman module, 10 times more sensitive as the previous, reduces analysis time to less than 1 second. This is particularly recommended when analyzing particles between 2µm and smaller than 5μm in diameter.

Image Analysis:

The result of the automated measurement is available within approx. 2 hours of analysis time.

A total of 800 particles were selected for analysis, the majority being protein particles, the primary source of contamination.
