Summary:Results obtained by repeated determinations of H2O, CO2, and SO2 evolved from a submarine basaltic glass (average sample mass = 3 X 10-3 g) from Kilauea volcano, Hawaii, gave probable errors for the determinations of H2O (0.23%), CO2 (0.025%), and S (0.071%) equal to 4, 10, and 8% respectively, of the concentrations. The principal advantages of this analytical technique are the very small sample required, the simultaneous determination of H2O, CO2, SO2 and noncondensable gas (H2, CO, N2, Ar, CH4, etc.), the avoidance of calibration procedures dependent on chemical standards, and the visual observations that can be made during sample outgassing.
