Inline particle size measurement with 180° DLS
In many manufacturing processes of dispersions, like printing inks or inkjet inks, there is a growing demand to measure the dispersions during the production in real time. This allows a very good and energy-efficient manufacturing. Furthermore, by continuous measurement an excellent quality assurance of process and end product will be given. A common measurement method of inkjet inks is measuring the particle size of the pigment which has a direct influence on the colour. The new IPAS sensor head, can be directly integrated in the manufacturing process for particle sizing. First tests with the new IPAS sensor head have already been done and published. A sample with a size of 300 nm particle diameter was measured in an unstirred sample with the normal DLS sensor and also in a stirred sample with the IPAS sensor head. In these test measurements we can see very well that the new IPAS sensor head can now be used in moved media.
