Figure 1-2. Impact of particle size reduction on the Van Deemter curves. These experimental curves were obtained with a mobile phase: H2O/MeCN (60:40 v/v), with butylparaben 25 ppm in H2O, UV detection: 254 nm, columns: XTerra RP18 4.6 mm x 150 mm, 5 um; XTerra RP 18 4.6 mm x 50 mm, 3.5 um; Acquity Shield bridged ethylsiloxane/ silica hybrid C18 2.1 mm x 50 mm, 1.7 um.
