Abstract The relaxation properties of agar gels render it a potentially useful basic reference material for calibrating the NMR equipment. The T 1 and T 2 values are close to the values observed for most biological tissues; they are stable and can be varied by controlling the concentration of MnCl 2 . The temperature, concentration, and volume dependence of T 1 and T 2 were studied.
