The results of calibration of 4He in desorption system show that the correlation coefficient is more than 0.99 and the contribution of memory effect can be ignored. The contribution of ionized atom T(superscript +) for partial pressure of m/e=3 is very little and is determined according to I+≈0.01I(subscript T2)+, so the measurement of 3He can be done without interference of T(superscript +). The relationship between gases release rate and annealing temperature can be obtained after the data are smoothed and differentiated.
