When properly explained, however, gradient elution can be less difficult to understand and much easier to use than often assumed.Written by two well-known authorities in liquid chromatography, High-Performance Gradient Elution: The Practical Application of the Linear-Solvent-Strength Model takes the mystery out of the practice of gradient elution and helps r 606 $aHigh performance liquid chromatography 615 0$aHigh performance liquid chromatography. 676 $a543/.84 700 $aSnyder$b Lloyd R$075155 701 $aDolan$b John W$0278317 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910143567103321 996 $aHigh-performance gradient elution$9759045 997 $aUNINA
