摘要: Methods of determining an amount of precursor in an ampoule have been provided herein. In some embodiments, a method for determining an amount of solid precursor in an ampoule may include determining a first pressure in an ampoule having a first volume partially filled with a solid precursor; flowing an amount of a first gas into the ampoule to establish a second pressure in the ampoule; determining a remaining portion of the first volume based on a relationship between the first pressure, the second pressure, and the amount of the first gas flowed into the ampoule; and determining the amount of solid precursor in the ampoule based on the first volume and the remaining portion of the first volume.
