Hydrophobic and Hydrophilic Compound Separation

September 25, 2003

Primesep 100 separates a mixture of polar and nonpolar compounds in one analytical run. The amino acid cysteine; amino acid derivatives L-cystine, 2,2-dimethylcystine, and 2-methylcysteine; the polar acid benzoic acid; and the nonpolar neutral toluene are separated by a gradient using a combination of polar and hydrophobic interactions. The separation method uses a mobile phase mixture of water, acetonitrile (MeCN, ACN) and sulfuric acid (H2SO4) with UV detection at 210 nm.

Condition
Column Primesep 100, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer H2SO4
Flow Rate 1.0 ml/min
Detection UV 210 nm
