Line-start incremental centrifugal

Line start-incremental monitoring system centrifugal disk photosedimentometers yield direct information on the largest and smallest fineparticle present in system. They can be operated in the fingerprint mode that is, the pen recorder traces for good and bad powders in a quality control situation can be established and compared directly to the traces generated by powder samples taken from production run. 

In homogeneous, incremental, centrifugal techniques matters are more complex since the particles move in radial paths hence the measured concentration is less than the original concentration (Figure 7). This problem does not occur with centrifugal line-start method at a fixed measurement radius.
