I have truck tire particles that I am using in my column experiment. I am trying to do size determination using the Malvern Zetasizer. My sample concentration is 0.1 mg/L, i.e., 10 g of sample was mixed with 100 mL of ultrapure water. I sonicated the sample for five minutes and some of the particles agglomerated. So, what filter size should I use to properly measure and get the representative particle size in my sample?

We worked with tire particles to regenerate rubber. These particles are very large and are not suitable for sizing in the Malvern Zetasizer. They do not mix well with water because they are hydrophobic. Ultrasonic dispersion will not help reduce particle size.
To study the size distribution of your particles, you are better off using sedimentation analysis.The methodology for performing sedimentation analysis is described in detail in

If your system starts dry then laser diffraction is the better light scattering technique here.
Thank you, Yuri Mirgorod. The link you provided, however, does not open.
Indeed, the particles are hydrophobic and do not mix well with water.

o determine your air filter size, you need to measure its length, width, and depth. These measurements are usually printed on the side of the filter. If not, you can use a tape measure to get the dimensions.
