Zusammenfassung:Methods for producing a product ingot from a silicon melt held within a crucible are disclosed. The methods involve evaluating one or more ingot puller apparatus to determine if the apparatus is capable of producing low oxygen content silicon product ingots. A sample rod is pulled from the silicon melt and the oxygen content of the sample rod is measured.
