The “tail” of a particle size distribution refers to particles several standard deviations removed from the mean of the standard Gaussian distribution. The larger, or oversize particles to the far right of the distribution are within the coarse tail. These are often the “bad actors” that cause problems with either product quality or performance. The fines tail are the smaller particles to the far left of the distribution that can also cause problems with product behavior such as powder flow.
This webinar will explain the statistics of distribution tails and the best analytical techniques to accurately quantify their presence. Example samples and industries will include emulsions, inks, CMP slurries, and powders used for additive manufacturing.
This webinar will cover a range of topics, including:
- Defining tails, coarse and fine
- How oversize particles cause problems
- How fines cause problems
- Measurement techniques
- Pharmaceutical industry standards
Who should attend:
Excessive amounts of coarse particles can cause a variety of problems with product performance including delayed dissolution, reduced print resolution, and clogging of orifices. Fines can impede powder flow and cause dusting problems.
This webinar is for scientists and engineers involved with particle-based products where either coarse or fine particles cause quality or processing problems. Particle characterization techniques for detecting tails in distributions and examples will be presented showing the optimum high-resolution technique for detecting these tails.
