A comparison of slow and fast transverse relaxation times for different agarose concentrations and dependence of visibility Visibility^SQ(ΔM_o/Δ[Na]) and visibility^IR(ΔMo/Δ [Na]) on agarose concentration. Visibility^SQand visibility^IRfor all concentrations of agarose were obtained using SQ and IR techniques. All transverse relaxation time constants T_2s^SE, T_2s^SEand T_2s^IR, T_2s^IRwere determined by single quantum Hahn spin echo and IR pulse sequence on NMR.
