Focusing methods

Because of the use of the focusing method [18], more than four calculations are actually carried out for each group. However, the focusing method saves computer time by permitting the use of less extensive finite-difference grids.

It is possible to use a hybrid of the plane wave and focused methods to study cells, by operating at modest values of positive defocus (Litniewski and Bereiter-Hahn 1990). Provided the reflecting surfaces, starting with the top of the cell, are a few wavelengths or more away from the focus of the lens, the effect of defocus is primarily to reduce the effective aperture of the lens.

On-column injection demands the use of large-diameter tubes to permit the penetration of the injection syringe needle into the column. However, this procedure also causes other problems to arise. On injection, the sample readily separates into droplets which act as separate, and individual, injections that cause widely dispensed peaks and serious loss of resolution. In the extreme, double or multiple peaks are formed. Grob [1] suggested two solutions to this problem the retention gap method of injection and the solute focusing method.
