The PowderJet dry powder feeder is a sampler used to transport powders through the HORIBA LA-950 for particle size analysis. The best dry powder feeder on the market just got better thanks to three significant design improvements. First, the upper air pressure limit has been increased from 3 to 4 bar (approximately 60 psi).
This supplies more energy to help disperse strongly agglomerated particles. Powder particles as small as 0.5 micron can be perfectly dispersed and analyzed in a natural dry state. Secondly, the user can now select any pressure desired between 0 and 4 bar. This allows finer tuning of the method based on the optimum pressure for dispersion without breaking particles. Thirdly, the air pressure selected and used for measurement is recorded and displayed in the result, assuring consistent sampler settings for any given powder sample.
These improvements expand upon the existing feature set of the state of the art PowderJet. Unique features include; automatic feedback control to adjust the speed of powder flow in real-time to produce unbeatable measurement precision, auto-measurement sets the measurement conditions once, then clicking a single button automatically obtains a particle size result, and small and large particle accessories for sizing powders as small as 200 nm and as large as 3 mm.
