Table 1 A comparison of slow and fast transverse relaxation times for different agarose concentrations and dependence of visibility VisibilitySQ (ΔMo/Δ[Na]) and visibilityIR (ΔMo/Δ [Na]) on agarose concentration. VisibilitySQ and visibilityIR for 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.
