HPLC Column EVOKE C18, 100 Å, 5 µm, 3.0 x 100 mm

Evoke C18 columns are manufactured using high purity silica and endcapped using a unique gas-phase technology. Gas-phase endcapping leads to improved surface coverage, shielding acidic silanol groups for a highly inert, hydrophobic surface that results in excellent separation kinetics and provides unique selectivity in comparison to other C18 phases. Additionally, it allows the use of higher concentrations of organic mobile phase for greater sensitivity by electrospray ionization mass spectrometry and improved loading capacity for preparative applications.
