Validation of the extended Tanaka column characterization protocol by multivariate analysis of chromatographic retention of low-molecular-weight analytes on reversed phase columns using methanol and acetonitrile as organic modifiers
The validity of the extended Tanaka column characterization procedure against the retention behavior of 101 analytes of widely differing properties chromatographed on five differing stationary phase chemistries has been established using a chemometric technique called principal component analysis (PCA). It was concluded that the simple and conveniently determined column characterization parameters covered the same space...
Practical implications of the “Tanaka” stationary phase characterization methodology using ultra high performance liquid chromatographic conditions
The practical implications of performing column characterization protocols (i.e. Tanaka) and their resultant chromatographic selectivity parameters using small dimension columns (i.e. 50 x 2.1 mm I.D.) at high pressures have been critically compared to those obtained using conventional LC methodology. Retention factors should be corrected for the system extra column volume even when determined on...
