In the field of inhalation research it is necessary to characterize unambiguously the inhalable aerosols regarding particle size distribution and concentration.
The scattered light spectrometer Inas ® has been especially developed for the inhalation research as well as the quality assurance of nebulizers and inhalers. With Inas ® the size distribution and the concentration of sprays can be determined in a quick, easy and reliable manner. Particles can be measured in the range of approx. 200 nm – 40 µm with high particle size resolution and temporally resolved. Even with spray bursts of inhalers a temporally resolution can also be of great interest. For this reason this system provides a temporally resolution of 10 ms.
Thus, for example, it is possible to evaluate the particle size distribution of a spray burst at the beginning and the end of the spray burst.
