Book Review

Microring Resonators Sensor array chips and the Maverick M1 optical scanning instrumentation were purchased from Genalyte, Inc. Classic liquid chromatography has several severe limitations as a separation method. The isocratic method is usually successful in the separation of sample molecules that unusual in their affinity for High-Performance Gradient Elution stationary phase. Note that this does not apply to HiTrap columns.

Cleaning Correct preparation of samples and buffers and application of a high salt wash 1 M NaCl at the end of each separation should keep most columns in good condition. The use of high pressures in a narrow column allowed for a more effective separation to be achieved in much less time than was required for previous forms of liquid chromatography. He then poured additional solvent into the column until the samples were eluted at the bottom of the column.

10 it is assumed that the gradient steepness factor is a constant and independent of compound identity, which will be true if all compounds have the same S-value.

Although temperature is the least effective parameter for changing selectivity the simultaneous optimization of temperature and solvent strength is a straightforward process using computer simulation [ 621—625]. Li and Cai [ 91] and Chu and Poole [ 92] used linear solvent strength theory to demonstrate a relationship between the gradient retention time or CHI and the solvation parameter model.

This allows S-values and log k w to be determined as a function of temperature and then retention to be predicted for all High-Performance Gradient Elution conditions and any temperature. The basis of this relationship is the colinearity between the change in solvent strength during a linear gradient and the approximate effect of the strong solvent on retention in isocratic RPLC described by Eq.
