# Question #954ed

Just to retire this question, a high molecular weight compound would have a mass far greater than $32 \cdot \text{amu}$....
Besides, below $32 \cdot \text{amu}$ you are going to observe ions from the elemental gases, i.e. ${N}_{2}^{+}$, ${O}_{2}^{+}$, etc....there will be a lot of competing peaks.........
