Abstract: A jones matrix is obtained using coefficients of an equalizer; a parameter of the jones matrix is obtained; a coefficient of an X axis polarization state or a Y axis polarization state in the coefficients is adjusted using the parameter of the jones matrix when the coefficients have singularity characteristics, or energy corresponding to each coefficient of X or Y axis polarization state under each order of a filter in the equalizer is determined using two coefficients of an X or Y axis polarization state in the equalizer coefficients; and a central position of a coefficient tap of X or Y axis polarization state of the equalizer is adjusted using the energy corresponding to each coefficient of X or Y axis polarization state under each order of the filter when the coefficient tap of the X axis or Y axis polarization state of the equalizer deviates from the central position.

Abstract: Novel material for chromatographic separations, processes for its preparation, and separation devices containing the chromatographic material. In particular, the novel materials are porous silicon oxynitride materials, which desirably can be surface modified and have enhanced stability at high pH. The novel porous silicon oxynitride material may offer efficient chromatographic separations, and hold great promise as packing material for chromatographic separations.
