Figure 1-8. 3D representation of the temperature profiles along and across various chromatographic columns (A) 150 mm x 2.1 mm (BEH) bridged ethylsiloxane/ silica hybrid-C18 column, flow rate = 0.95 mL/min, Pinlet = 979 bar. (B) 100 mm x 2.1 mm BEH-C18 column, flow rate = 1.45 mL/min, Pinlet = 1005 bar. (C) 50 mm x 2.1 mm BEH-C18 column, flow rate = 2 mL/min, Pinlet = 775 bar. The experimental setup used to measure the temperature of the surface of the column and the temperature of the liquid exiting the column outlet is also shown.
