Fig. 5.

Release profiles of 4He from individual snow-AMMs measured using stepwise heating at the temperatures of 400, 500, 600, 700, 800, and 1600°C with the miniature furnace (Fig. 2). The release profiles are separated into three groups according to released amounts of 4He; High 4He (on the order of 10−3 cm3 STP/g), Medium 4He (10−4 cm3 STP/g), and Low 4He (10−5 cm3 STP/g). Errors are 1σ.
