Removal of small particles using a 20-μm mesh column. Particle distributions from identical samples of ‘Iwafune-15’ clone were determined without (a and c; magenta) and with (b and c; green) passage through the 20-μm mesh column. Merged sample data are shown in c and d. The X axis indicates particle diameter (μm) and the Y axis indicates particle count. The limit of the Y axis is 750 counts in a–c and 70 counts in d. Peaks of the small debris section (0–20 μm) are indicated by magenta (without 20-μm mesh column) and green (with 20-μm mesh column) arrows in c
