The relationship is time-of-flight X where m is the mass of the ion. Hence flight times of and s are expected for H O and OH respectively. Time-of-flight data for the eV ESDIED peak also shows that H is being desorbed but that O and or OH are probably not. ESD Applications. The data acquired for the polycrystalline tin oxide sample discussed in the previous section is discussed further here. Consider the ESDIED and time-of-flight data shown in Fig. 29. The data were acquired after annealing for 30 min at 600 C 1110 F and X 10-7 Pa X 10-9 torr . Note that the eV ESDIED peak is very small relative to the higher-energy peak around eV. The time-of-flight data of Fig. 30 and 31 show that O and OH are both desorbed and the eV peak has more O than OH relative to the eV .
